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: -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-3: -As a result, there is a net gain of two ATP molecules during glycolysis. During this stage, high-energy electrons are also transferred to molecules of NAD+ to produce two molecules of NADH, another energy-carrying molecule.
Detailed explanation-4: -Since 2 pyruvates are produced from glucose during glycolysis, a total of 4 are made from our 2 glucose molecules. These 4 pyruvates are then converted to 4 acetyl-CoA molecules. Each of these acteyl-CoA molecules runs through the Krebs cycle yielding a total 12 molecules of NADH.
Detailed explanation-5: -Thus, the correct answer is ‘2. ‘
