Question

The conversion of 1 mol of pyruvate to 3 mol of CO2 via pyruvate dehydrogenase and the citric acid cycle yields ___mol of NADH, ____mol of FADH2, and ___mol of ATP (or GTP).

A. 3; 2; 0
B. 4; 2; 1
C. 4; 1; 1
D. 3; 1; 1
E. 2; 2; 2

Answer 1

Answer: Option C.

4 mol of NADH, 1 mol FADH2 and 1 mol of ATP.

Step-by-step explanation:

Pryruvate dehydrogenase is an enzyme that convert pyruvate to acetyl CoA by a process called private decatboxylation. This take place in the mitochondria. Pyruvate dehydrogenase convert 1 mol of pyruvate to 3 mol of Co2.

Critic acid cycle or kreb cycle is the series of reaction that produce energy through the oxidation of acetyl CoA produced from pyruvate dehydrogenase conversion in living organisms. Citric acid cycle produce ATP and reduced form of 1 mol of FADH2 and 4 mol of NADH.
