                Enzymes enhance the rate of a reaction by:

A)                                                                                                         lowering the activation energy of the reaction  

B)                 combining with the product as soon as it is formed

C)                 forming a reactant-product complex      

D)                 changing the equilibrium point of the reaction

Correct Answer: A
