Each NADH and FADH2 produced from the CAC yields approximately 3 and 2, respectively. Thus, if there is 3 NADH, 1 FADH2, and 1 GTP made from the CAC, each complete cycle yields about 10-12 ATP molecule (or their equivalent). WebUnlike glycolysis, the citric acid cycle is a closed loop: The last part of the pathway regenerates the compound used in the first step. The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH 2 ( Figure ). phillip walker carnell
