First, the glucose is broken down. Scientists refer to this step as glycolysis. Then, the second process, aerobic respiration breaks the remains of the glucose down further. During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose.
The pyruvate from one molecule of glucose drives two turns of the Krebs cycle. Thus, during cellular respiration one molecule of glucose, as well as oxygen, ADP, and free phosphate are catabolized to yield six molecules of carbon dioxide and an increase in usable energy in the form of eight molecules of ATP.
