Question

Identify the proteolytic enzyme present in the gastric juice.
1. Peptidase
2. Trypsin
3. Chymotrypsin
4. Pepsin

Answer 1

Correct Answer - Option 4 : Pepsin

Concept:

• The proteolytic enzyme pepsin is found in the gastric juice of all vertebrates.
• The central or the chief cells of the gastric mucosa secrete the inactive precursor pepsinogen which on the cleavage of a peptide inhibitor and other neutral peptides is converted to the proteolytically active pepsin.
• Proteolytic enzymes help break proteins down into smaller protein fragments called peptides and amino acids.
