Most of the chemical energy released by the citric acid cycle is in the form of ATP.

Question

Quizplus · Accepted Answer

The citric acid cycle generates energy in the form of ATP as well as electron carriers such as NADH and FADH2. However, most of the chemical energy stored in these molecules is actually released in the subsequent process of oxidative phosphorylation, which takes place in the mitochondria and produces much larger amounts of ATP. Therefore, it would be more accurate to say that most of the chemical energy generated by cellular respiration (including the citric acid cycle) is ultimately transferred to ATP through oxidative phosphorylation.
