Detailed explanation-1: -Answer and Explanation: The citric acid cycle breaks down pyruvic acid into carbon dioxide and produces NADH, FADH, and ATP.
Detailed explanation-2: -Products and Functions of the Krebs Cycle For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
Detailed explanation-3: -All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules.
Detailed explanation-4: -Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH, and two H2O. Therefore, without the presence of oxygen, glycolysis is the only process that can occur, and only two ATP molecules may be produced for each glucose molecule.
