Question

Why do enzymes act upon energy of activation

Answer 1

In the presence of an enzyme, the Activation energy is lowered. thus the reactions reaches the activation energy and the reaction is initiated faster and therefore completes faster than the reactions without enzymes. Enzymes lower activation energy, which allows a reaction to occur at a faster rate.

Answer 2

Enzymes lower the activation energy of a reaction by binding one of the reactants, called a substrate, and holding it in a way that lowers the activation energy. ... Likewise, an enzyme holds its substrate in such a way that the reaction is much more likely to occur.
