In order to completely oxidize glucose, it takes two turns of the citric acid cycle, which yields a net of two ATP, six NADH and two FADH₂. How many of the 32 total ATP molecules produced in cellular respiration come from the citric acid cycle, including the contribution from the NADH and FADH₂?

Question

Quizplus · Accepted Answer

The citric acid cycle produces 2 ATP directly, and the 6 NADH and 2 FADH2 yield 18 ATP and 4 ATP respectively through oxidative phosphorylation, totaling 24 ATP from the cycle.
