Text Solution

Verified by Experts

The correct Answer is:
B
(B) ATP Production in respiration

1. Isocitrate to a-ketoglutarate: 2NADH `rarr` 6ATP
2. `alpha`-Ketoglutarate to succinyl CoA: 2NADH `rarr` 6ATP
3. Succinyl CoA to succinic acid `rarr` 2ATP
4. Succinic acid to fumaric acid : `2FADH_(2) rarr` 4ATP
Oxidation of one molecule of pyruvic acid produces 15 ATP.
Oxidation of one molecule of acetyl CoA produces 12 ATP.
