Most of the ATP derived from the breakdown of glucose in aerobic cells is derived from glycolysis.

Question

Quizplus · Accepted Answer

While glycolysis is the first step in glucose breakdown, most of the ATP produced in aerobic cells is actually derived from the citric acid cycle and oxidative phosphorylation, which occur in the mitochondria. Glycolysis produces a net gain of only 2 ATP molecules, whereas the citric acid cycle and oxidative phosphorylation can produce a much larger amount of ATP.
