Problem 13 Tutorial: 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:

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.
