The Krebs cycle, which is also known as the citric acid cycle or tricarboxylic acid cycle, is part of a series of chemical reactions that organisms use to break food down into a form of energy that cells can use.
In carbohydrate metabolism, acetyl CoA is the link between glycolysis and the citric acid cycle. The initiating step of the citric acid cycle occurs when a four carbon compound (oxaloacetic acid) condenses with acetyl CoA (2 carbons) to form citric acid (6 carbons). The whole purpose of a turn of the citric acid cycle is to produce two carbon dioxide molecules.
