Question
In oxidation -reduction reactions, each time a substance is oxidized, another is simultaneously reduced. Which of the below substances is in the reduced form and therefore the electron donor?Group of answer choicesNADHNAD+
Solution
The substance in the reduced form and therefore the electron donor in this case is NADH. In the context of oxidation-reduction reactions, NADH is the reduced form of NAD+. This means that NADH has gained electrons (and is therefore an electron donor), while NAD+ has lost electrons (and is therefore an electron acceptor).
