Correct option is D)
(A) Enzymes are proteins that catalyze biological reactions. Thus, the option A is correct. (B) Enzymes act efficiently at a optimum value of temperature and pH. Thus, option B is incorrect. (C) Co-enzymes do not increase the activities of enzymes. They help enzymes in the catalytic activity. Co-enzymes bind to the active site of the catalyst and participate in the enzyme activity. Thus, option C is incorrect. (D) Enzymes are highly specific in their action on substrates. Thus, option D is correct.
