biochemical reactions that break down acetyl groups to produce energy carried by reduced coenzymes and carbon dioxide
The citric acid cycle, also known as the tricarboxylic acid (TCA) cycle or the Kreb's cycle is the pathway responsible for the breakdown of Acetyl CoA. Acetyl CoA enters the cycle by condensing with oxaloacetate to for citrate. In the cycle, 2 molecules of carbon dioxide are released and NADH and FADH2 are produced. These nucleotide coenzymes enter the electron transport chain where ATP is produced. See lesson 4. See also: ATP; Electron transport
Another term for the Krebs Cycle.
Another name for the Krebs cycle, named for the first product of the cycle, citric acid.
The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle, after Hans Adolf Krebs who identified the cycle) is a series of chemical reactions of central importance in all living cells that use oxygen as part of cellular respiration. In aerobic organisms, the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production, the other two being glycolysis and oxidative phosphorylation.
