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.
Glucose is oxidized during glycolysis. What molecule has been reduced? In other words, what molecule collects the electrons (reduced) that have been stripped off of the glucose molecule (oxidized)? 2. . Describe how pyruvic acid, a three carbon molecule, (each of the two that was derived from glycolysis) becomes acetyl CoA. 3. Describe the electron transport chain in the mitochondrial membrane by answering the following questions:
