TCA Cycle

Q1: The FADH2 and NADH produced by the oxidation of one acetyl-CoA results in the synthesis of about-

A 3 ATPs

B 6 ATPs

C 11 ATPs

D 15 ATPs

ANS:C - 11 ATPs

The FADH2 and NADH produced by the oxidation of one acetyl-CoA results in the synthesis of about;

3 NADH are produced = 7.3 ATPs.
1 FADH2 is produced = 1.5 ATP,

Total ATPs produced = 9 ATP.

This is very different from the total number of ATPs produced in TCA which is:

3NADH + 1FADH2 + 1 ATP = 10 ATPs.
