Indicate if the following coenzymes are involved in reduction (R) or in oxidation (O) reactions: NADPH; FAD; NAD+.
NADPH: It is a Reduciing agent.So it involved in reduction reactions.
FAD: It is a very strong oxidizing agent. So it involved in oxidation reactions.
NAD+: It is one of natures most important oxidizing agent. So it involved in oxidation reactions.
