Question

What is the name given to that part of the enzyme where catalytic work is carried out?

Answer 1

Hint: Enzymes are biocatalysts which affect the rate of any chemical reaction. They are one of the biomolecules. In any chemical reaction, they help in achieving the results faster. They have a special site where all these catalytic reactions take place.

Complete answer:
To know the correct answer of the question, we must be aware of the enzymes and their catalytic activity.
Enzymes are also catalysts which alter the rate of the chemical reaction either speeding them or slowing them. They have a pocket which is made up of a specific sequence of amino acids. This is the place where the catalytic work takes place. This pocket is known as the active site of the enzyme.
The substrate is the molecule that binds to this active site and catalytic work is carried on it. Now when the enzyme attaches to the substrate, it forms an enzyme substrate complex. This complex modifies the substrate and yields the product.
This entire process takes place on the active site. The active site is different for different substrates and hence the enzymes are substrate specific. The sequence of the amino acid which make up the active site should correspond to the amino acid sequence on the substrate otherwise catalysis would not take place.

Therefore, the correct answer to the question is the active site.

Note: The enzymes work by lowering the activation energy of the reaction. Activation energy of any reaction is the minimum amount of energy required for the reaction to take place. By lowering this activation energy the rate of the reaction is increased.
