The citric acid cycle (CAC)—also known as the Krebs cycle or the TCA cycle (tricarboxylic acid cycle) —is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or ae… WebFor every NADH and FADH 2 that are produced in the citric acid cycle, 2.5 and 1.5 ATP molecules are generated in oxidative phosphorylation, respectively. At the end of each cycle, the four-carbon oxaloacetate has been regenerated, and the cycle continues. Steps [ edit] There are ten basic steps in the citric acid cycle, as outlined below.
