Which of the following enzymes catalyse the hydrolysis of peptide bonds present in proteins and polypeptides?

Correct option is D

Proteases are enzymes that catalyze the hydrolysis of peptide bonds in proteins and polypeptides. They break down proteins into smaller peptides or individual amino acids.

Information Booster:

1. Proteases are also called peptidases or proteinases.
2. Found in organisms ranging from bacteria to humans, with roles in digestion and cellular processes.
3. Examples include trypsin, chymotrypsin, and pepsin.
4. These enzymes are used in the food industry for tenderizing meat and cheese production.
5. Protease inhibitors are essential in medicine, e.g., for treating HIV.

Additional Knowledge:

• Glucoamylases: Break down starch into glucose.
• β-Galactosidase: Catalyzes the breakdown of lactose into glucose and galactose.
• α-Amylases: Break down starch into maltose and dextrin.
