 Citric acid cycle - Wikipedia, the free encyclopedia
The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle) is a series of chemical reactions of central importance in all living cells that utilize 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.
The citric acid cycle is also known as the Krebs cycle after Sir Hans Krebs (1900-1981), who proposed the key elements of this pathway in 1937 and was awarded the Nobel Prize in Medicine for its discovery in 1953.

Acontinase - The citric acid cycle enzyme responsible for catalyzing the reaction that converts citric acid to isocitrate with the release of water.
Citric acid cycle - Also known as the Krebs Cycle; a metabolic pathway found in aerobic organisms that oxidizes acetyl coA groups to carbon dioxide and water, producing 1 ATP, and a number of coenzymes that play a vital role in the next step of respiration, oxidative phosphorylation.
Over the course of a series of reactions, the citric acid is broken back down into two CO molecules and oxaloacetate, allowing for the cycle to being again while producing ATP and a number of coenzymes.
