When Nad reacts wit hydrogen and gains two electrons Nad is hydrolyzed reduced oxidized or phosphorylized?

When Nad (nicotinamide adenine dinucleotide) reacts with hydrogen and gains two electrons, it is reduced. This process involves the addition of electrons, which decreases the oxidation state of the molecule. Hydrolysis refers to the reaction with water, phosphorylation involves the addition of a phosphate group, and oxidation is the opposite of reduction. Therefore, in this context, Nad is specifically undergoing reduction.
