A)1 ATP, 2 CO₂, 3 NADH, and 1 FADH₂ 
B)2 ATP, 2 CO₂, 3 NADH, and 3 FADH₂ 
C)3 ATP, 3 CO₂, 3 NADH, and 3 FADH₂ 
D)3 ATP, 6 CO₂, 9 NADH, and 3 FADH₂ 
E)38 ATP, 6 CO₂, 3 NADH, and 12 FADH₂

Quizplus · Accepted Answer

Each acetyl CoA entering the citric acid cycle produces 1 ATP (or GTP), 2 CO₂, 3 NADH, and 1 FADH₂. Therefore, three acetyl CoA molecules would produce 3 ATP, 6 CO₂, 9 NADH, and 3 FADH₂.
