What is activation energy? how does an enzyme affect the activation energy in a chemical reaction?

Explanation:

Activation energy is defined as the minimum amount of energy necessary to initiate a chemical reaction.

Protein molecules that function like a catalyst are known as enzymes. Enzymes help in carrying a biochemical reaction without itself getting consumed.

Enzymes bind at the specific site of a substrate and helps in lowering the activation energy so that, more and more reactant molecules can participate in the reaction. As a result, formation of products become more rapid.
