The result of five turns of the citric acid cycle would be A) 5 ATP, 5 NADH, 5 FADH₂, 5 carbon dioxide. B) 5 ATP, 15 NADH, 5 FADH₂, 10 carbon dioxide. C) 10 ATP, 30 NADH, 10 FADH_2, 20 carbon dioxide. D) 10 ATP, 10 NADH, 5 FADH_2, 10 carbon dioxide. E) 15 ATP, 15 NADH, 15 FADH_2, 15 carbon dioxide

Question

Quizplus · Accepted Answer

Each turn of the citric acid cycle generates 3 NADH, 1 FADH2, 1 ATP (or GTP), and 2 CO2. Therefore, after five turns, the cycle would produce 15 NADH (3 NADH x 5), 5 FADH2 (1 FADH2 x 5), 5 ATP (1 ATP x 5), and 10 CO2 (2 CO2 x 5).
