Step 1 Introduction

Enzymes : It is a substance that acts as a catalyst in living organisms , regulating the rate at which chemical reactions proceed without itself being altered in the process . Enzymes catalyze all aspects of cell metabolism.

Activation energy : The minimum energy needed for a reaction to proceed , known as activation energy . It stays the same with increasing temperature . An increase in temperature causes a rise in the energy levels of the molecules involved in a reaction , so the rate of the reaction increases.
