The citric acid cycle (Kreb’s cycle or tricarboxylic acid-TCA cycle) is the most important cyclic metabolic pathway for the energy supply to the body. During the eight reactions that take place, for every molecule of acetyl-CoA the cycle produces three NADH and one flavin adenine dinucleotide (FAD/FADH2), along with one molecule of ATP.
