Detailed explanation-1: -As pyruvic acid is a three carbon atom containing molecule and acetyl CoA is a two carbon atom containing molecule, when one molecule of pyruvic acid is converted to one molecule of acetyl CoA, one molecule of carbon dioxide is released.
Detailed explanation-2: -The different fates of pyruvate and other end products of glycolysis. The glycolysis module left off with the end-products of glycolysis: 2 pyruvate molecules, 2 ATPs and 2 NADH molecules.
Detailed explanation-3: -For each glucose at the beginning, end products are 2 pyruvates, 2 ATP, and 2 NADH. Between glycolysis and the citric acid cycle (Pyruvate oxidation): Pyruvates from glycolysis enter the inner compartment of the mitochondrion. One carbon atom is removed, and 2 NADH are generated.
Detailed explanation-4: -1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
Detailed explanation-5: -Two molecules of pyruvate are converted into two molecules of acetyl CoAstart text, C, o, A, end text. Two carbons are released as carbon dioxide-out of the six originally present in glucose.
