Introduction

Enzymes are biomolecules that increase the rate of a reaction by reducing the activation energy required for the reaction. Most enzymes are protein molecules, on rare occasions, they are also RNA which is also known as ribozymes. 

Enzymes are secreted by all living organisms, including unicellular bacterias. The involvement of enzymes is not limited to metabolism, they are vital for DNA replication in the cell cycle as well.
