Answer:
Option (e).
Explanation:
Enzymes may be defined as the biocatalyst that are used during the metabolic reaction of the body. Most of the enzymes are proteinaceous in nature.
The main function of the enzyme is to lowers the activation energy of the reaction. The lowering of the activation energy reduces the energy barrier and substrate can be converted into the product easily. Hence, enzymes also increases the rate of a reaction.
Thus, the correct answer is option (e).
