Question

Why is the citric acid cycle called a cycle?

Answer 1

The Krebs cycle forms (per two molecules of
pyruvic acid ) 2 ATP molecules, 10 NADH
molecules, and 2 FADH molecules. ... The
reason the Krebs cycle is a cycle is because
oxaloacetic acid (oxaloacetate) is the exact
molecule needed to accept an acetyl-CoA
molecule and start another turn of the cycle .
