The TCA cycle is also known as the tricarboxylic acid cycle. The TCA cycle oxidizes the acetyl Co-A into carbon dioxide along with the generation of reducing equivalents in the form of NADH and FADH2. The TCA cycle occur in the mitochondrial matrix only in the presence of oxygen or aerobic environment.

- Understanding the Oxidation of Glucose and Its Products in the TCA Cycle Glycolysis, the pyruvate dehydrogenase reaction, and the TCA cycle result in complete oxidation of a molecule of glucose to CO2. Review the calculation of oxidation numbers for individual atoms in any molecule, and then calculate the oxidation numbers of the carbons of glucose, pyruvate, the acetyl carbons of acetyl-CoA. and the metabolites of the TCA cycle to convince yourself that complete oxidation of glucose involves removal of 24 electrons and that each acetyl-CoA through the TCA cycle gives up 8 electrons.Complete oxidation of a 16-carbon fatty acid can yield 129 molecules of ATP Study Figure 19.2 and determine how many ATP molecules would be generated if a 16-carbon fatly acid were metabolized solely by the TCA cycle, in the form of S acetyl-CoA molecules.The number of CO2 molecules liberated for each molecule of acetyl-CoA during oxidative decarboxylation reactions in TCA cycle.
