Question

Enzyme pepsin belongs to category

• A. oxidoreductases
• B. transferases
• C. hydrolases
• D. isomerases

Answer 1

The correct option is C hydrolases

Hydrolases are any class of enzymes which catalyze the hydrolysis of proteins, nucleic acids, starch, fats, phosphate esters, and other macromolecular substances. The hydrolysis is carried out through the addition of water. Digestive enzymes carry out their function in this way, hence they are called hydrolase.
Pepsin is an endopeptidase that breaks down proteins into smaller peptides. It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans. Hence pepsin belongs to the category of hydrolases.

Oxidoreductases are the group of enzyme which catalyse oxidoreduction between two substrates.

Transferases are the group of enzyme which catalyses transfer of a group (other than hydrogen) between a pair of substrate.

Isomerases are the group of enzymes which catalyses inter-conversion of optical, geometrical or positional isomers.
