Explanation:
Detailed explanation-1: -NADH(2) generated in glycolysis produces ATP in ETS in presence of O(2).
Detailed explanation-2: -In glycolysis, 3-phosphoglyceraldehyde (PGAL) is oxidized to 1, 3-bisphosphoglycerate, which results in the production of 2 NADH molecules (BPGA).
Detailed explanation-3: -During the conversion of 3-phosphoglyceraldehyde to 1, 3-bisphosphoglycerate, two redox equivalents (i.e., two electrons) are passed onto NAD+ from 3-phosphoglyceraldehyde to form NADH.
Detailed explanation-4: -Hence, the correct answer is ‘2’
