alleryDuring the conversion of pyruvic acid to acetyl-CoA, which gas is released?
ACarbon dioxide
BOxygen gas
CHydrogen gas
DNitrogen gas
Answer & Solution
Correct answer: A. Carbon dioxide
1. Pyruvic acid from glycolysis is converted to acetyl-CoA.
2. During this step two molecules of NADH2 and two molecules of CO2 are released.
3. Oxygen is consumed in aerobic respiration, not released here, so it is ruled out.
