Detailed explanation-1: -The two forms of NAD constitute a redox couple. This term is used to describe reduced and oxidized forms of the same molecule. The NAD+ Is the oxidized form, that is, a state in which it loses an electron. NADH is a reduced form of the molecule, which means that it gains the electron lost by NAD+.
Detailed explanation-2: -Oxidation is when a molecule loses electrons, such as when NADH loses its hydride to become NAD+. In this example, we say that NADH is oxidized to NAD+.
Detailed explanation-3: -The necessary reduced form of NAD is Nicotinamide adenine dinucleotide hydrogen or NADH. It is significantly reduced NAD with unique high-energy hydrogen that interacts with the oxygen molecule to synthesize energy.
Detailed explanation-4: -NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the Krebs cycle.
