Lab 5 Cellular Respiration

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule, such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, and fats can all be metabolized as fuel, but cellular respiration is most often described as the oxidation of glucose, as follows: C6H12O6 + 6O2 > 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain.Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into twopyruvate (3-C). The Krebs cycle is also a catabolic pathway that occurs in the mitochondrial matrix and completes glucose oxidation by breaking down apyruvate derivative (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substra te-level phosphorylation and NADH by transferring electrons from substrate to NAD+ (Krebs cycle also produces FADH2 by transferring electrons to FAD).The electron transport chain is located at the inner membrane of the mitochondrion, accepts energized electrons from reduced coenzymes that are harvested during glycolysis and Krebs cycle, and couples this exergonic slide of electrons to ATP synthesis or oxidative phosphorylation. This process produces 90% of the ATP. Cells respond to changing metabolic needs by controlling reaction rates. Anabolic pathways are switched off when their products are in ample supply. The most common mechanism of control is feedback inhibition.Catabolic pathways, such as glycolysis and the Krebs cycle, are controlled by regulating enzyme activity at strategic points. A key control point of catabolism is the third step of glycolysis, which is catalyzed by an allosteric enzyme, phosphofructokinase. The ratio of ATP to ADP and AMP reflects the energy status o f the cell, and phosphofructokinase is sensitive to changes in this ratio. Citrate and ATP are allosteric inhibitors of phosphofructokinase, so when their concentration rise, the enzyme slows glycolysis.As the rate of glycolysis slows, the Krebs cycle also slows since the supply of Acetyl-CoA is reduced. This synchronizes the rates of glycolysis and the Krebs cycle. ADP and AMP are allosteric activators for phosphofructokinase, so when their concentrations relative to ATP rise, the enzyme speeds up glycolysis, which speeds of the Krebs cycle. Cellular respiration is measure in three manners: the consumption of O2 (how many moles of O2 are consumed in cellular respiration? ), production of CO2 (how many moles of CO2 are produced in cellular respiration? , and the release of energy during cellular respiration. PV = nRT is the formula for the inert gas law, where P is the pressure of the gas, V is the volume of the gas, n is the number of molecules of gas, R is the gas constant, and T is the temperature of the gas in degrees K. This law implies several important things about gases. If temperature and pressure are kept constant then the volume of the gas is directly proportional to the number of molecules of the gas. If the temperature and volume remain constant, then the pressure of the gas changes in direct proportion to the number of molecules of gas.If the number of gas molecules and the temperature remain constant, then the pressure is inversely proportional to the volume. If the temperature changes and the number of gas molecules is kept constant, then either pressure or volume or both will change in direct proportion to the temperature. Hypothesis: The respirometer with only germinating peas will consume the largest amount of oxygen and will convert the largest amount of CO2 into K2CO3 than the respirometers with beads and dry peas and with beads alone.The temperature of the water baths directly effects the rate of oxygen consumption by the contents in the respirometers (the higher the temperature, the higher the rate of consumption). Materials: The following materials are necessary for the lab: 2 thermometers, 2 shallow baths, tap water, ice, paper towels, masking tape, germinating peas, non-germinating (dry) peas, glass beads, 100 mL graduated cylinder, 6 vials, 6 rubber stoppers, absorbent and non- absorbent cotton, KOH, a 5-mL pipette, silicon glue, paper, pencil, a timer, and 6 washers. Procedure:Prepare a room temperature and a 10oC water bath. Time to adjust the temperature of each bath will be necessary. Add ice cubes to one bath until the desired temperature of 10oC is obtained. Fill a 100 mL graduated cylinder with 50 mL of water. Add 25 germinating peas and determine the amount of water that is displaced. Record this volume of the 25 germinating peas, then remove the peas and place them on a paper towel. They will be used for respirometer 1. Next, refill the graduated cylinder with 50 mL of water and add 25 non-germinating peas to it.Add glass beads to the graduated cylinder until the volume is equivalent to that of the expanded germinating peas. Remove the beads and peas and place on a paper towel. They will be used in respirometer 2. Now, refill the graduated cylinder with 50 mL of water. Determine how many glass beads would be required to attain a volume that is equivalent to that of the germinating peas. Remove the beads. They will be used in respirometer 3. Then repeat the procedures used above to prepare a second set of germinating peas, dry peas and beads, and beads to be used in respirometers 4,5,and 6.Assemble the six respirometers by obtaining 6 vials, each with an attached stopper and pipette. Then place a small wad of absorbent cotton in the bottom of each vial and, using the pipette or syringe, saturate the cotton with 15 % KOH. Be sure not to get the KOH on the sides of the respirometer. Then place a small wad of non- absorbent cotton on top of the KOH-soaked absorbent cotton. Repeat the se steps to make the other five respirometers. It is important to use about the same amount of cotton and KOH in each vial. Next, place the first set of germinating peas, dry peas and beads and beads alone in vials 1,2, and 3.Place the second set of germinating peas, dry peas and beads, and glass beads in vials 4,5, and 6. Insert the stoppers in each vial with the proper pipette. Place a washer on each of the pipettes to be used as a weight. Make a sling using masking tape and attach it to each side of the water baths to hold the pipettes out of the water during the equilibration period of 10 minutes. Vials 1,2, and 3 should be in the bath containing water at room temperature. Vials 4, 5, and 6 should be in the bath containing water that is 10oC. After the equilibration period, immerse all six respirometers into the water completely.Water will enter the pipette for a short distance and stop. If the water does not stop, there is a leak. Make sure the pipettes are facing a direction f rom where you can read them. The vials should not be shifted during the experiment and your hands should not be placed in the water during the experiment. Allow the respirometers to equilibrate for three more minutes and then record the initial water reading in each pipette at time 0. Check the temperature in both baths and record the data. Every five minutes for 20 minutes take readings of the water’s position in each pipette, and record.Results: In this activity, you are investigating both the effects of germination versus non-germination and warm temperature versus cold temperature on respiration rate. Identify the hypothesis being tested on this activity. The rate of cellular respiration is higher in the germinating peas in cold than in the beads or non-germinating peas; the cooler temperature in the cold water baths slows the process of cellular respiration in the both germinating and non-germinating peas. This activity uses a number of controls. Identify at least three of the controls, and describe the purpose of each.The constant temperature in the water baths yielding stable readings, the unvarying volume of KOH from vial to vial leading to equal amounts of carbon dioxide consumption, identical equilibration periods for all the respirometers, precise time intervals between measurements, and glass beads acting as a control for barometric pressure all served as controls. Describe and explain the relationship between the amount of oxygen consumed and time. There was a constant, gradual incline in the amount of oxygen consumed over precise passage of time.Why is it necessary to correct the readings from the peas with the readings from the beads? The beads served as a control variable, therefore, the beads experienced no change in gas volume. Explain the effects of germination (versus non-germination) on pea seed respiration. The germinating seeds have a higher metabolic rate and needed more oxygen for growth and survival. The non-germinating peas, t hough alive, needed to consume far less oxygen for continued subsistence. Above is a sample graph of possible data obtained for oxygen consumption by germinating peas up to about 8oC. Draw in predicted results through 45oC.Explain your prediction. Once the temperature reached a certain point, the enzymes necessary for cellular respiration denatured and germination (and large amounts of oxygen consumption) was inhibited. What is the purpose of KOH in this experiment? The KOH drops absorbed the carbon dioxide and caused it to precipitate at the bottom of the vial and no longer able to effect the readings. Why did the vial have to be completely sealed under the stopper? The stopper at the top of the vial had to be completely sealed so that no gas could leak out of the vial and no water would be allowed into the vial.If you used the same experimental design to compare the rates of respiration of a 35g mammal at 10oC, what results would you expect? Explain your reasoning. Respiration wou ld be higher in the mammal since they are warm-blooded and endothermic. If respiration in a small mammal were studied at both room temperature (21oC) and 10oC, what results would you predict? Explain your reasoning. Respiration would be higher at 21 degrees because it would be necessary for the animal to maintain a higher body temperature.The results would proliferate at 10 degrees because the mammal would be required to retain its body temperature at an even lower temperature in comparison to room temperature. Explain why water moved into the respirometer pipettes. While the peas underwent cellular respiration, they consumed oxygen and released carbon dioxide, which reacted with the KOH in the vial, resulting in a decrease of gas in the pipette. The water moved into the pipette because the vial and pipette were completely submerged into the bath. Design an experiment to examine the rates of cellular respiration in peas that have been germinating for 0, 24, 48, and 72 hours.What res ults would you expect? Why? Respirometers could be set up with respirometer 1 containing non-germinating peas, respirometer 2 holding peas that have been germinating 24 hours, 3 would contain the peas that germinated 48 hours, and 4 would hold the peas that germinated 72 hours. All the respirometers should have the KOH added to the bottom in the same manner as in lab described earlier. The respirometers should be placed in baths with the same temperature for all the respirometers. The seeds that have not begun germination would consume very little oxygen.The peas that have been germinating for 72 hours will have the greatest amount of oxygen consumption, while the other two samples will consume a medium (in comparison to respirometers 1 and 4 results) amount of oxygen. Error Analysis: Numerous errors could have occurred throughout the lab. The temperature of the baths may have been allowed to fluctuate, the amounts of peas, beads, KOH, and cotton may have varied from vial to vial da maging the results, and these problems would have occurred only during set up. Air may have been allowed to creep into the vial via a leaky stopper or poorly sealed pipette.Timing for the equilibration of the respirometers and the five-minute time intervals may have been erroneous. It was somewhat difficult to read the markings on the pipettes and so errors are always likely. Mathematical inaccuracies may have taken place when filling out the table and finding the corrected difference by using the formula provided. Discussion and Conclusion: The lab and the results gained from this lab demonstrated many important things relating to cellular respiration. It showed that the rates of cellular respiration are greater in germinating peas than in non- germinating peas.It also showed that temperature and respiration rates are directly proportional; as temperature increases, respiration rates increase as well. Because of this fact, the peas contained by the respirometers placed in the water at 10oC carried on cellular respiration at a lower rate than the peas in respirometers placed in the room temperature water. The non-germinating peas consumed far less oxygen than the germinating peas. This is because, though germinating and non-germinating peas are both alive, germinating peas require a larger amount of oxygen to be consumed so that the seed will continue to grow and survive.In the lab, CO2 made during cellular respiration was removed by the potassium hydroxide (KOH) and created potassium carbonate (K2CO3). It was necessary that the carbon dioxide be removed so that the change in the volume of gas in the respirometer was directly proportional to the amount of oxygen that was consumed. In the experiment water will moved toward the region of lower pressure. During respiration, oxygen will be consumed and its volume will be reduced to a solid. The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube.The respirometer with just the glass beads served as a control, allowing changes in volume due to changes in atmospheric pressure and/or temperature. This activity uses a number of controls. Identify at least three of the controls, and describe the purpose of each. The constant temperature in the water baths yielding stable readings, the unvarying volume of KOH from vial to vial leading to equal amounts of carbon dioxide consumption, identical equilibration periods for all the respirometers, precise time intervals between measurements, and glass beads acting as a control for barometric pressure all served as controls.Describe and explain the relationship between the amount of oxygen consumed and time.

Militarization of Our Police Essay

I strongly feel that military tactics, training, and equipment do not have a place in American law enforcement because dozens of needless deaths and injuries have occurred because of it and it’s extremely expensive to supply these things. First, the American law enforcement has become much too aggressive with its citizens. There are several reports of police going above and beyond, using extreme measures, to take down the general public. One perfect example would be the MacDonald case. In the summer of 2006 a frail, troubled 18-year-old girl named Ashley MacDonald ran through a nearly empty Huntington Beach, California, city park in the early morning holding a small knife. An onlooker called the police and soon two large male officers showed up. They shot the girl to death with 18 bullets, claiming she had lunged toward them and put their lives in danger (Greenhut, 2008). Another example showing excessive, military force being used would be the Jose Guerena case. The home of former Marine and Iraq combat veteran Jose Guerena was raided by local sheriffs in Pima County, Arizona, who were attempting to execute a narcotics search warrant. Unfortunately, the manner in which the SWAT team invaded Guerena’s home prompted Guerena to reach for his gun to protect himself and his family. Sheriffs then shot off 71 rounds and hit Guerena with 22, killing him (Clabough, 2011). Second, it has cost the government millions of dollars to supply the American law enforcement with military equipment, which I believe is completely unnecessary. According to Pentagon data cited by The Daily, the Defense Department gave away almost $500 million worth of surplus military equipment to state and local law enforcement in 2011, which was a new record. And next year’s orders are already up more than 400 percent (Newman, 2011). The crime rate may have decreased, but the detailed numerous accounts of abuses and failed operations that left innocent people dead and the record billions worth of military equipment still being handed to local police is absolutely ridiculous. I feel there is more bad than good deriving from the militarization of our police.

Les Murray’s “The Widower in the Country” Essay

In â€Å"The Widower in the country†, change is conveyed in many ways. The poem shows that change can bring a life of isolation and loneliness. The poem also shows how change is not always embraced and how we should not lead a life with a lack of change. The title of the poem, the widower in the country immediately gives the reader the impression of an individual in a vast area. This lets the readers know that the widower is alone and isolated. Already, the reader already feels sympathy for the widower, not only because he has lost his wife, but he now lives alone in a vast and empty area. In the first stanza, the first line, â€Å"I’ll get up soon, and leave my bed unmade†, shows how the persona leads a life that is monotonous and repetitive each day. There is a certainty and reluctance in his tone and it seems as though he now has no reason to make his bed, as he is lonely and there is no one who will see the bed even if it was made. At the end of the stanza, â€Å"For I get up late now†, the word â€Å"now† has been deliberately placed to show how the widower has changed his behaviour. In the second stanza, the personification of â€Å"Christmas paddocks, aching in the heat†, imitates the personas own feelings, and the words â€Å"aching in the heart† look like aching in the heart, which is what the persona feels like, as he has lost his wife. Christmas is also usually a time for family gathering, and this highlights how change has caused the widower to lead a life of loneliness and isolation. This stanza is also filled with negative imagery and mundane activities- â€Å"The windless trees, the nettles in the yard†¦ and then I’ll go in, boil water and make tea.† The †¦ at the end of the sentence shows that the widowers day is filled with other activities that are more or the same, again highlighting his life that has a lack of change. The lack of punctuation in this stanza also reflects the widower’s monotonous life and again shows how change can bring a life of isolation and loneliness. In the third stanza, there is again a lack of punctuation. â€Å"I’ll stand out on the hill and watch my house away below, and how the roof reflects the†.  There is a certainty in the widower’s tone and the detached images show he doesn’t want to be in this situation. â€Å"Makes my eyes water† gives us an image of the widower in misery and crying and we feel sympathy for him. This also shows he has not embraced the change. â€Å"Close on bright webbed visions smeared on the dark of my thoughts to dance and fade away† shows how the persona has visions and memories of the past. There is a paradox between bright and smeared and this reflects the persona’s misery. Although he wishes to think of the happier times in the past, they have now become blurred and have faded away. â€Å"Then the sun will move on† shows the widowers unhappiness and â€Å"I will simply watch, or work, or sleep† is a cumulative listing of three monotonous and mundane activities, which highlights the lack of variety in the widower’s life. The sentence also shows how the monotony is never-ending. In â€Å"And evening will come on† the â€Å"and† is placed at the start of the sentence to draw attention to how the widower is so certain about his life as it is always the same, day after day. In the last stanza, â€Å"Getting near dark, I’ll go home, light the lamp and eat my corned-beef supper, sitting there at the head of the table† shows how the widower’s day is filled with even more mundane activities and his reluctance to make any changes. The fact that he is sitting at the head of a table highlights his loneliness, as he has no family, and is by himself. â€Å"Then I’ll go to bed† again shows the certainty in his tone and his lack of change. â€Å"Last night I thought I dreamed† is the only time there is a change in tense and harsh sounding images- â€Å"the screaming was only a possum ski-ing down the iron roof† follows it. The widower has lost all hope as he cannot even dream and has nothing positive to look forward to, not even in his dreams. The poem ends with its only positive image â€Å"little moonlit claws†. With uses of imagery, personification, paradox, assonance and cumulative listing, Les Murray’s â€Å"The Widower in the Country† clearly shows how change can lead to a life of isolation and loneliness.

How do diplomacy,economic policies and military action work together Research Paper

How do diplomacy,economic policies and military action work together in the United States foreign policy - Research Paper Example To date, we consider the US as the strongest economic power on the global sphere as well as the strongest nation in the entire world in terms of wars. She has the most sophisticated machinery and military personnel’s than any other country in the world. She has as well the strongest army in the world. Above all, the economy of America has overtaken any economy in the entire world at present. The world’s economic base is pegged on the dollar monopoly whereby the US dollar is used as the world’s medium of exchange and for business transactions across the entire globe. It is only the United States currency which has been accepted as the medium of exchange for all international business transactions and not the other currencies. Even though the European pound is also used for international business transactions, it is the US dollar which dominates the global market. The European pound has only been used to a limited scale especially among the nations making up the Eu ropean Union and a few of her colonies. Heo and Karl (2004) argue that the stability of the United States monopoly of the world has however been threatened by some other rising world economies (Heo and Karl 2004). These other small economies which have been rising to keep at purr with the US economy include that of Japan and China. These economies however have not reached the levels of being able to control the world economy as the United States has managed. There is power in the extent or the area of land and the total population commanded by a state to be considered powerful. The small economies mentioned above have not been able to make it to the global sphere because of their small land sizes as well as their small populations. In terms of military specialization and war dominations, the world has been looking forward to the development of nuclear weapons for purposes of war. Many nations considered to be among the strongest nations in the world have developed very technical and sophisticated war machines. Wang has listed some of these such as South Korea among others. These countries have as well developed very lethal nuclear weapons which have been considered a major source of threat to the entire world (Wang 1999). As a result there have been rumors of wars as well as some other wars fought between various nations of the world. The rumors of wars are what the political analysts and war experts refer to as the cold war and begun some years ago. In order to maintain the economic, political and military power, the united states knows very well that she has to employ certain techniques to enable her survive in her position. This paper will investigate how the United States of America has been using her political, economic and diplomatic mechanisms in her foreign policies to rue the entire world and to establish herself as the world’s super power. 2 The monopoly of the US economy and military power has been threatened by some countries today forcing t he US to revise her stand on how she controls and rule the world. Some of the states which have posed threats to US of late include Iran, Syria among others (Kegley 1998). These are mostly the Arab nations. These countries have made America to realize the need to strengthen her missions abroad and change the overall process of monitoring the world’

Justification for Recommendation - Assignment Example A learning scenario is a prioritized description of a situation in learning, which is independent of any underlying pedagogical approach. The scenario describes an organization with the aim of ensuring the appropriation of prà ©cised set of skills, competence, and knowledge. The learning scenario in this case is a practical learning scenario. A practical learning scenario consists of descriptions followed by respective questions although the scenario could develop in stages with each stage having at least one question (Shepherd, 2011). Information may be presented with the use of various media elements such as texts but the described situation has to be relevant and realistic. In theory, various formats of questions could be employed in order to challenge learners about the situation being learned including the simple multi-choice questions. Any of the various theory formats are meant to determine the abilities of students in their capacity to answer various forms of questions (Leje une A., 2004). In this learning scenario, the learning objectives involve the determination of the ability of students to answer various forms of questions. The objective includes expectations that lie within the outcome of the education program. The paper will establish the capacities that students have in handling questions in different forms as part of their assessment program within a practical learning scenario (Shepherd, 2011 ).

Critically assess the main implications of globalisation for HRM, and Essay - 1

Critically assess the main implications of globalisation for HRM, and analyse the future challenges for people management within - Essay Example The main implications of globalization for HRM are in terms of people management and in taking care of the day to day affairs of the organization, which essentially mentions where shortcomings and apprehensions arise and how best to do away them in a convenient way (Richter, 2006). This paper highlights how globalization has affected HRM and how several employee levels within an organization work to their best possible levels to bring that vital change which is much needed. Also significance is laid on different premises like cultural manifestations, people to people linkages, role of top management and specialists, and the usage of resources for the overall betterment of the organizations and the productivity basis of the employees in the long run. It is significant to first define how globalization has affected HRM. With the advent of time and age, globalization has influenced each and every segment of life and professional domains are no exception to this rule. Similarly, HRM gets its basis from the professional regimes where emphasis is on getting the job done for the sake of people management, which includes recruiting, firing and so on. ... The main implications of globalization for HRM depend a great deal on how globalization is viewed in essence and how it is able to resolve the ambiguities which stand in the way of HRM dependence. There is a dire need to comprehend the fact that HRM will take care of all such nuances if handled in an amicable fashion. Also the manner in which HRM will manifest its truest role is something that goes to show how things are deemed as important under the aegis of the workplace discussions. Globalization has indeed come out as an eye-opener for many organizations around the world and it is for this reason that there are immensely significant pointers that shall be discussed and delved deep upon in this paper. When HRM is seen from a global perspective, different employees are hired who belong to distinctive cultures from around the world. How they are managed is an interesting phenomenon which needs to be seen from the organizational and industrial standpoints. These employees do find it hard to adjust within various workplace locations yet are always willing to bring a change within their personalities and domains to suit the needs and requirements of the organizations they work for. The earnestness on their part to bring about a change is always present. The need is to comprehend how to set things right within the organizational settings so that HRM presents a true picture. Globally speaking, HRM is always given preference within an organization because it creates an instructional basis for the employees and tells them the difference between the right and the wrong. It is a fact that those organizations which have many employees on board usually look up to their HRM domains in order to bring sanity within recruitment, day to day people management and

Piety and Impiety Essay Example | Topics and Well Written Essays - 1250 words - 1

Piety and Impiety - Essay Example This meant he was more likely to face the consequences of his actions as those against him yielded the power to prosecute him. According to Plato’s (Socrates close friend) account, Socrates prosecution was masterminded by Anytus, a leading democrat. In the years before Socrates trial, the Tyrants had taken over Athens, these were lead by Critias, a former pupil of Socrates (Brickhouse and Smith 26). Many of the Athenians who supported the democrats and the democrats who were overthrown by the tyrants viewed Criatias actions as emanating from Socrates teachings. The fact that Critias made it clear that he had cast aside the follies of his youth, such as education, did not change the Athenians view of Socrates role in the growth of the tyrants. Soon after, the Tyrants were replaced by the democrats. As a sign of reconciliation and a means of healing the wounds of the civil war Socrates perceived role was sidestepped. However, Anytus who was a leading voice among the democrats wa s not as forgiving. His actions were not only a result of the civil war but were mostly personal as his son was a keen follower of Socrates teachings. ... The first of these charges was impiety. Under impiety, Socrates was accused of believing in multiple gods of which the state never believed in.
