Krebs cycle is a part of cellular respiration that takes place in the mitochondria.
Five energy conversions take place in one complete cycle of the Krebs cycle.
These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.
Thus, total 10 energy conversions would occur in two rounds of Krebs cycle or when 2 molecules of acetyl-CoA go through the cycle.
