Cellular Respiration Essay

Our data recorded shows that the germinating peas did consume more oxygen than the non-germinating or the glass beads alone and that the cooler temperature did slow down the consumption of oxygen in the germinating peas. In both water baths the atmospheric pressure seemed to increase causing our reading to raise in our glass beads and non-germinating peas. This direct relationship in reading leads us to believe that the oxygen consumption in the non-germinating peas was minimal if any at all.

Aim: The aim of this experiment is to investigate the effect of changing the temperature on the rate of respiration in yeast. This will be done by placing equal amounts of yeast in each beaker that contains the same pH solution. Each beaker will be mixed with glucose solution and then will be placed at a different temperature in which the amount of CO2 produced will be measured every one minute.

4. Describe and demonstrate cellular respiration and energy production in plants including aerobic and anaerobic pathways.

Respiration was measured in germinating seeds in the Pea Lab because in germinating peas there is a high rate of cell respiration as the pea is still growing and needs to consume oxygen to continue growing. Pea plant cells rely on the process of cellular respiration to supply them with the energy that they need to stay alive and grow during germination. When the pea plants are grown the cells will still remove energy from sugar via cellular respiration; however, the sugar for cellular respiration will come from the process of photosynthesis instead of the stored

First glucose is broken down in the process called glycolysis, then the pyruvate molecules are moved to the mitochondria, when this is happening the pyruvate molecules are converted into 2-carbon molecules these molecules then enter the Kreb Cycle. Moving on the energy created will now enter the electron transport chain, this energy will then produce ATP. The reactants are glucose and oxygen and the products are ATP, water, and carbon dioxide. During the Cellular Respiration glucose is being oxidized, along with carbon. On the other hand Oxygen, NAD+ and FADH are being reduced in Cellular Respiration.

Organisms are complex and use energy to function, grow, and reproduce. Organisms get this energy from photosynthesis and cellular respiration. Photosynthesis is the process by which plants harness sunlight to make glucose from carbon dioxide and water1. Photosynthesis provides glucose for cellular respiration. Glucose is the reactant for cellular respiration. Cellular respiration has complex stages, where the glucose molecule is slowly broken down. The formula for cellular respiration is C6H12O6 + 6O2 ⇢ 6CO2 + 6H2O + energy.

The purpose of the Cell Respiration Comparison was to test the respiration of different types of organisms with different conditions. The importance of testing the respiration was to know in what types conditions the organisms could respire the best. The way that we found out which organism respired the best was by using a Labquest that calculated the respiration rate. When calculating the respiration rate, we found that germinating peas with room temperature respire at a higher rate than germinating peas with a cold temperature. With our findings we can conclude that the temperature affects an organism's respiration

Cellular respiration is a key cellular process that allows for the production of ATP that is used to power many other anabolic and catabolic activities. Respiration must be performed by all living cells in order to provide the necessary energy for the cell, but there are different forms of respiration that can be used by cells in differing circumstances. These forms include fermentation, anaerobic respiration, and anaerobic respiration. These different actions each produce ATP and function using similar actions. However, each of these processes hold substantial pieces that make them their own type of activity. These processes all use glycolysis and recycle NAD+, but yield different amounts of ATP and recycle NAD+ in different ways.

Part A: The average American consumes almost 2000 pounds of food each year. Luckily, we do not gain 2000 pounds of weight each year! What happens to all the weight of the food we eat?

If you were to combine the yeast with the sugars in milk would the yeast grow, and if so how would it affect the cellular respiration? We need to look into what yeast needs to grow, cellular respiration in yeast, and the sugar in milk to find the answer to this problem. The solution to this problem could find a better way to produce yeast for the world.

All living organisms such as prokaryotic and eukaryotic cells require energy to carry out a large number of activities to help them survive daily. Cellular respiration is a process that provides cells with energy to full fill these requirements for survival. Cellular respiration is an exergonic reaction that extracts chemical energy stores in the covalent bonds of organic nutrients such as sugars,fats. and amino acids, and transfers it into bonds of ATP. ATP provides energy that drives nearly all biochemical reactions in cells and synthesis of macromolecules.

This experiment consisted of 3 respirometers, one with ants, one with radish seeds, and one with glass beads. Each with 4 pellets of KOH and a piece of cotton. They were placed in a water bath that was at 75 degrees fahrenheit. A bubble at the end of the respirometer was measured every five minutes, and this distance showed how well the organisms were respiring. The radish seeds were able to do the most cellular respiration in 25 minutes, with the ants being a close second, and the control respirometer of the glass beads doing the least.

1. 5 sucrose solutions were made of increasing molarity: 0.2 M, 0.4 M, 0.6 M, 0.8 M, 1.0M. 2. 50 mL of each unknown solution were poured into 5 separate cups. A slice of potato was placed into 5 equal cylinders. 3. The mass of the 5 potato cylinders were then recorded. 4. The cylinders were placed into the foam cups with solution and covered with plastic wrap. It is to be left overnight. 5. The room temperature was recorded in Celsius. 6. The cylinders are then to be removed from the cups and carefully blotted of any excess solution. 7. The mass of the potato cylinders were recorded afterwards.

Cellular respiration is a procedure that most living life forms experience to make and get chemical energy in the form of adenosine triphosphate (ATP). The energy is synthesized in three separate phases of cellular respiration: glycolysis, citrus extract cycle, and the electron transport chain. Glycolysis and the citric acid cycle are both anaerobic pathways because they do not bother with oxygen to form energy. The electron transport chain however, is aerobic due to its use of oxidative phosphorylation. Oxidative phosphorylation is the procedure in which ATP particles are created with the help of oxygen atoms (Campbell, 2009, p. 93). During which, organic food molecules are oxidized to synthesize ATP used to drive the metabolic reactions necessary to maintain the organism’s physical integrity and to support all its activities (Campbell, 2009, pp. 102-103).
