The [[Citric Acid Cycle]] (tricarboxylic acid cycle) is a series of enzyme catalyzed reactions which are critical in cellular respiration. Under oxidative conditions, pyruvate continues to be metabolized through the tricarboxylic acid cycle. In this cycle, Acetyl-CoA, a byproduct of [[glycolysis]], along with various cofactors, are broken down into carbon dioxide, water, and energy in the form of GTP and NADH. | The [[Citric Acid Cycle]] (tricarboxylic acid cycle) is a series of enzyme catalyzed reactions which are critical in cellular respiration.
