Testing Cell Respiration and Alcoholic Fermentation

The energy yielding metabolism function in which oxygen is used is known as cell respiration. With each turn of the cycle there is use of oxaloacetate. An example of this is glucose metabolism, which can be divided into three parts. Once it is phosphorylated the glucose splits into tow 3-carbon fuels that are later oxidized by enzymes and phosphorylated. The chemical expression for cell respiration is: C6H12O6 + 6O2 yields to 6CO2 + 6H2O + Chemical Energy. Located along the inner membrane of the mitochondrion are numerous electron transport systems.

The second part of glucose metabolism is the citric acid cycle. There will be four different tubes filled with four different yeast concentrations for the comparison of rates. The oxaloacetate joins with acetyl-CoA and when water enters the coenzyme A is released which forms citric acid. During glycolysis, glucose enters the pathway and gets phosphorylated by ATP twice. The products that are produced are protons and electrons.

The first part is glycolysis, which is the breakdown of glucose and substrate level phosphorylation and the formation of energy products. Their energy is used fro a proton gradient. As water enters and leaves the cycle ATP is formed.
