Hint There are many reactions in which the reactants convert into products that take a very long time for completion. But when the catalyst is added to the reaction the speed of the reaction increases, in the same way, enzymes which are biological catalysts also work.

Complete step by step answer:
In a chemical reaction, the reactants are converted into products and the completion of the reaction depends on the rate of the reaction. There are many reactions in which the reactants convert into products that take a very long time for completion. Some compounds which are catalysts are introduced to these reactions which increase the rate of the reaction in the same way enzymes which are biological catalysts also work.
So, enzymes are those special catalysts that are used to increase the rate of the reaction that takes place in our body or living organisms. We can also call the enzymes, biochemical catalysts. There are many types of reactions in the biological system and each reaction requires a different enzyme.
The reactant is converted into products when the reactant combines with each and overcomes the activation energy which is the minimum energy to form the product. So, the enzymes will decrease the activation energy of the reaction and increase the rate of the reaction. And the speed of the reaction will increase and the products will be formed in less time.

Note: Some examples of enzymes are Invertase, zymase, diastase, maltase, urease, etc. Invertase is used for the reaction of inversion of cane-sugar. Zymase is used for the conversion of glucose to ethyl alcohol.
