The Kreb's or the TCA cycle begins with the condensation of acetyl-CoA with Oxaloacetic acid (OAA) and water, which results in the formation of citric acid. The enzyme which catalyzes the reaction and also results in the release of the molecule CoA is citrate synthase. It is a pace-making enzyme and acts as a convenient handle for the carbon atoms to pass from enzyme to enzyme in the Kreb's cycle.
