1 Answer

Answer :

(2) Vitamins Explanation: Vitamins are organic molecules that function in a wide variety of capacities within the body. The most prominent function of the vitamins is to serve as cofactors (coenzymes) for enzymatic reactions. If an enzyme lacks the essential vitamin, it cannot perform its catalyst function properly.
