Which of the following statements is (are)True about enzyme-catalyzed reactions?
A)The reaction is faster than the same reaction in the absence of the enzyme.
B)The free energy change of the reaction is opposite from the reaction in the absence of the enzyme.
C)The reaction always goes in the direction toward chemical equilibrium.
D)A and B only
E)A, B, and C

Question

Quizplus · Accepted Answer

Enzymes can increase the rate of a reaction by lowering the activation energy required for the reaction to occur, making the reaction faster than the same reaction in the absence of the enzyme. However, enzymes do not change the direction in which a reaction proceeds, so option C is incorrect. Option B is also incorrect because the free energy change of the reaction is still the same with or without the enzyme, although the activation energy required for the reaction to occur may be different. Therefore, the correct answer is A.
