Problem 13: Storing Usable Energy
As a result of glycolysis, pyruvate oxidation and the citric acid cycle, only a small portion of the energy of glucose has been converted to ATP. At this point, the majority of the usable energy is contained in:
A. oxidized electron carriers NAD+ and FAD
B. carbon dioxide
C. pyruvate
D. acetyl Coenzyme A
E. reduced electron carriers NADH and FADH2
Usable energy after the citric acid cycle
Oxidative phosphorylation produces the majority of the energy generated in the cell. The combination of glycolysis and the citric acid cycle alone yield only 4 ATP. The majority of the energy is stored in the electron carriers NADH and FADH2. Oxidative phosphorylation can produce 3 ATP for each NADH and 2 ATP for each FADH2.
