Scientific definitions for Krebs cycle

Krebs cycle

A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP. The Krebs cycle is the intermediate stage, occurring between glycolysis and phosphorylation, and results in the enzymatic breaking down, rearranging, and recombination of byproducts of glycolysis. The combination of glycolysis and the Krebs cycle ultimately allows 36 ATP molecules to be produced from the energy contained in one molecule of glucose and six molecules of oxygen. Also called citric acid cycle See more at cellular respiration.
