How many ATP molecules are produced per Krebs’ Cycle in eukaryotes?

How many ATP molecules are produced per Krebs’ Cycle in eukaryotes? Correct Answer 24 ATP

A total of 6 NADH, 2 ATP, and 2 FADH2 molecules are being produced. 3 ATP molecules are produced per NADH molecules. Thus, 18 (6X3) ATP molecules are produced as Krebs’ cycle produces 6 NADH molecules. 1 FADH2 molecule produces 2 ATP, so for 2 FADH2 molecules, 4 ATP molecules are produced. 2 GTP molecules equivalents to 2 ATP molecules produced in Krebs’ cycle. Thus, in one Krebs’ cycle, (18+4+2) = 24 molecules of ATP are produced.
