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.
The citric acid cycle also produces 2 ATP by substrate phosphorylation. Fig. 1: The Citric Acid Cycle (Also Known as the Tricarboxylic Acid Cycle and the Krebs Cycle). Copyright Â© Gary E. Kaiser. 1. Before the pyruvates from glycolysis can feed into the citric acid cycle, they must undergo a transition reaction.The pyruvate is converted into a 2-carbon acetyl group as the third carbon is lost as CO 2. The acetyl group is attached to coenzyme A to form acetyl-CoA.efore the pyruvates from glycolysis can feed into the citric acid cycle, they must undergo a transition reaction.
