It will begin with a brief outline of the four processes involved in cellular respiration, followed by a discussion on the various steps and reactions involved in each process in greater detail and it will conclude with a summary of the events. The oxidation of glucose is known as cellular respiration.
Glycolysis is the oxidation of glucose to pyruvic acid and occurs in most cells in the body.
The formation of acetyl coenzyme A from pyruvic acid is a transition step between glycolysis and the Krebs cycle that prepares pyruvic acid for entrance into the cycle. Both the Krebs cycle and the electron transport chain require oxygen to produce ATP, they are therefore referred to as aerobic cellular respiration. The reactions of glycolysis use two ATP molecules and in turn produce four, a net gain of two ATP molecules. The enzyme used to catalyze this reaction is hexokinase. The enzyme used to catalyze this reaction is phosphoglucomutase.
