Explanation:
Detailed explanation-1: -In glycolysis, 3-phosphoglyceraldehyde (PGAL) is oxidized to 1, 3-bisphosphoglycerate, which results in the production of 2 NADH molecules (BPGA).
Detailed explanation-2: -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-3: -Reaction to Transition: 2 NADH generates 6 ATP.
Detailed explanation-4: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
