Question

Enzymes enhance the rate of reaction by

(a) Forming a reactant-product complex

(b) Changing the equilibrium point of the reaction

(c) Combining with the product as soon as it is formed

(d) Lowering the activation energy of the reaction

Answer 1

Correct option  (d) Lowering the activation energy of the reaction

Explanation : 

Enzymes enhance the rate of a reaction by just lowering the activation energy (the energy required for substances to react and get converted into product) of a reaction.
