Question

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 is opposite from the reaction in the absence of the enzyme. c. The reaction always goes in the direction toward chemical equilibrium.

Answer 1

Answer : The correct option is A.

Explanation :

Enzyme-catalyzed reaction :

Enzyme act as a biological catalyst and the role of catalyst is to increase the rate of chemical reaction by lowering the activation energy.

Most of the chemical reactions are slow in the absence of enzyme but in the presence of enzyme, the reaction become faster. That means the Enzyme accelerate the rate of reaction.

Therefore, the correct answer is the reaction is faster than the same reaction in the absence of the enzyme.
