Based on Figure 9.11, which of the following molecules are direct net products of one complete turn of the citric acid cycle per acetyl CoA molecule?

  • A: 3 NADH, 1 FADH2, 1 ATP (or GTP), 2 CO2
  • B: 2 NADH, 1 FADH2, 1 ATP (or GTP), 1 CO2
  • C: 4 NADH, 2 FADH2, 2 ATP (or GTP), 4 CO2
  • D: 3 NADH, 2 FADH2, 1 ATP (or GTP), 2 CO2

Explanation

Per acetyl CoA molecule, the citric acid cycle directly produces 3 NADH steps 3, 4, and 8 , 1 FADH2 step 6 , 1 ATP or GTP, from step 5 , and releases 2 CO2 molecules steps 3 and 4 .
