Which of the following serves as an electron carrier in cellular respiration a ADP b Acetyl-CoA c NAD + d H2O

Answer: - NAD+

Explanation;

-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.

-NAD + and FAD; also the two most common electron carriers in the body. NAD + can accept a pair of electrons (and a hydrogen ion) to become NADH.
