Fill in the blanks with the pair of words below that make the following sentence correct: NADH is ________ compared to NAD⁺ because NADH has gained ________.

Quizplus · Accepted Answer

NADH is reduced compared to NAD⁺ because it has gained electrons. Oxidation refers to a loss of electrons, while reduction refers to a gain of electrons. Therefore, options A and B can be eliminated because they suggest NADH has lost electrons, while option D suggests it has gained neutrons, which is not possible for an already-formed molecule.
