Cellular Respiration My hypothesis for the germinated pea experiment was that the level of aerobic respiration would increase as the temperature would increase. I also predicted that there would be an upper temperature limit. The experiment proved part of my hypothesis correct and part of it incorrect. I was correct in predicting that the rate would increase as the temperature increase, but I was incorrect in hypothesizing that there would be an upper limit. My hypothesis for the larvae experiment was that the level of aerobic respiration would increase as the temperature increased and there would be an upper temperature limit. My hypothesis was proved to be correct, for the rate of respiration continued to increase until the upper limit was hit and the rate started to decline. There were no unexpected results from our group, but I noticed that group six had some unexpected data in the class larvae table. The only explanation I can make out of it is that the group made a math error. I do not have any suggestions to make this experiment better. Other factors that can affect the rate of cellular respiration are amount of available nutrients, because this allows more energy to be produced from the cell with an increase in amount of nutrients. Another factor is the state of the cell, such as the difference between working and dormant cells or the difference between plant and animal cells. From our data, we noticed that the temperature had an effect on the germinated Pisum sativum seeds. As the temperature increased, the rate of cellular respiration was doubled. At 45 degrees, the rate still increased, but it just barely increased. In the Zophobus morio we noticed that the rate increased from 10 degrees to 20 degrees. It then began to decrease as we continued to raise the temperature of the water. We got a negative amount for the…...

Metabolism and Oxidative Cellular Respiration

...Metabolism III: Oxidative Cellular Respiration Introduction Oxidative cellular respiration is composed of series metabolic processes that convert broken down food molecules into usable energy in the form of adenosine tri-phosphate (ATP). The process follows oxidation (catabolic) and reduction (anabolic) pathways. Processes involved are glycolysis, Krebs or tricarboxylic acid (TCA) cycle, and the electron transport chain. One step in the TCA cycle is the enzyme-catalyzed conversion of succinate to fumarate in a redox reaction. In intact cells succinate loses hydrogen ions and electrons to FAD to form fumarate. This step in the TCA cycle will be used to study the rate of cellular respiration under different conditions. (Patriquin, M. Rand, T. 2012). Since DPIP is a reducing dye it will absorb the hydrogen ions and electrons from the redox reaction of the TCA cycle between succinate and fumarate producing a discoloration of the dye. The discoloration is measured in percent transmittance of light over 30minutes at 5 minute intervals. The change in dye color is the associated with cellular respiration activity, and will be used to record the cellular respiration rate in mitochondria isolated from pulverized lima beans (Phaseolus lunatus) and subsequent effects of different substrate concentration, pH, and metabolic inhibitors . If the difference of light percent transmission produced by (DPIP) can be recorded over time associated with the cellular respiration rate......

Cellular Respiration

...Cellular Respiration Cellular respiration is the primary way that chemical energy is taken from food and turned into adenosine triphosphate, or ATP energy. ATP is the energy used to guide cells. Cellular respiration is a process that happens in a cell constantly. Without ATP energy, cells would not be able to function. The human race as well as plants and animals would die without this energy. In the process of cellular respiration, oxygen is required. A cell has to exchange two gases with its surroundings. The cell takes in oxygen in the form of the gas O2 and in turn, gets rid of waste in the form of the gas carbon dioxide, or CO2. This is similar to the process that the human body goes through. O2 is inhaled. O2 is carried to cells where it is used in cellular respiration. Carbon dioxide, which is a waste product of cellular respiration, is diffused from the cells and delivered to the blood and goes to the lungs where it is exhaled (Campbell). Cellular respiration is considered a very important process in cells. It protects the cell from harmful increases in temperature as well as provides the cell with a pathway of transferring energy in a controlled environment. The goal of cellular respiration is to break down carbohydrates into glucose, and use the glucose to produce ATP energy. Cellular respiration is made up of one glucose molecule which is added to six oxygen molecules. This equates to six carbon dioxide molecules, six water molecules, and 36-38......

Photosythesis an Cellular Respiration

...Linkage between Photosynthesis and Cellular Respiration The link between photosynthesis and cellular respiration is an inverse relationship. Each cycle depends on one another in order for the "entire cycle" to take place. The completed cycle make certain that life continues to exist on the planet. Both are necessary for living organisms. Photosynthesis is the process by which carbon dioxide is converted into organic compounds from sunlight. Photosynthesis occurs in plants, algae, and some bacteria. The process of photosynthesis is also the source of carbon in organic compounds in human bodies, as well as animals. Photosynthesis provides the oxygen for life and for the process of cellular respiration. The simplest way to explain photosynthesis is (Carbon dioxide + light energy → carbohydrates (sugar) + oxygen). Without photosynthesis, humans would cease to exist. Cellular respiration, in contrast, takes glucose (sugar) and other organic compounds oxidizing them to create carbon dioxide. Cellular respiration can be defined as metabolic reactions in organic cells which converts biochemical energy into adenosine triphosphate, better known as ATP. Cellular respiration also releases carbon dioxide into the atmosphere allowing plants, algae, and bacteria to process the carbon dioxide back into oxygen. The simplest way to explain Cellular Respiration is (Glucose + 6Oxygen --> 6Carbon Dioxide + 6Water). Photosynthesis and cellular respiration is a life cycle that keeps the......

...Blow Up a Balloon with Cellular Respiration Introduction: Yeasts are unicellular microorganisms of the fungi kingdom. They are facultative anaerobe, which means that they can respire or ferment depending upon environmental conditions. In the presence of oxygen, respiration takes place (aerobic respiration). Without oxygen present, fermentation occurs (anaerobic respiration). Both processes require sugar to produce cellular energy. Here is the chemical reaction of fermentation, which produces ethanol and carbon dioxide as metabolic waste products. Objective: In this lab, students will use the respiration powers of yeast to blow balloons. This activity will reinforce the basic principles of respiration as a fundamental metabolic process for living organisms using yeast as a model.

Cellular Respiration

...Cellular Respiration Class, today we are going to be talking about a really cool way your body breaks down food molecules into carbon dioxide and water! First, let’s understand what exactly this means. This process is called Cellular Respiration. This happens when food molecules, such as glucose (sugar in your body) breaks down into carbon dioxide, which is an odorless gas in the air, and water. And I’m sure you all know what water is, correct? (Giggle) That’s what I thought! Now that we all understand what that means, we are going to find out what happens next! Oh boy, who’s excited? Me too! Here we go! Once the molecules are oxidized into carbon dioxide and water, the energy released is trapped in a form ATP (which I’ll be discussing in just a few minutes) so it can be used by all the energy-consuming activities of the cell! We all know what a cell is correct? We all have cells in our body that help us function and stay alive! Well, when this happens, it occurs in two parts! First, the glucose breaks down to pyruvic acid. And everyone remembers what glucose is, right? That’s right, the sugar in our bodies! So let’s figure out of pyruvic acid is! It is a yellowish acid that occurs in metabolic processes, which is necessary for life! So it is very important for this part to happen, correct? There is another part of this we are going to be discussing next. The next step is when it completely oxidizes the pyruvic acid into the carbon dioxide and water! What color is the......

Cellular Respiration

...Cellular Respiration What is Cellular Respiration? Is the process of taking Oxygen and glucose and turning them into ATP, is energy to the body. The glucose is obtained from the food and food is breaking down to glucose to make ATP. Cellular respiration is 40% to efficient with 60% of the energy going to heat. This process happen in three stages the first one is Glycolysis, than Krebs cycle or Citric Acid cycle and the third one is Electron Transport Chain (ETC) Glycolysis is a series of chemical reactions in the cytoplasm of cells that breakdown glucose into two or more molecules of Pyruvic acid 4ATP molecules are proceed 2ATP molecules are used in the process, the net gain is 2ATP molecules,2NADH molecules are proceed. After Glycolysis there is an intermediate stage Pyruvic acid moves into mitochondria where it undergoes a series of chemical reactions that causes it to lose one CO2 molecule. This product combines with coenzymes A to form acetyl-CoA than is ready for the next step Krebs cycle. Krebs cycle is a series of reactions that breaks down Acetyl-CoA to form ATP, NADH and FADH2. One molecule of ATP is proceed, 3 molecules of NADH are proceed,1FADH2 molecules is proceed and the CO2 is by-product of the Krebs Cycle. The final stage is Electron Transport chain (ETC) is a series of proteins embedded in the mitochondria membrane. FADH2 and NADH carry electrons to the electron chain those electrons move down the chain and goes down to the final......
