Question

Pepsin present in gastric juice helps to

• A. combine amino acids to form protein
• B. activate pepsinogen
• C. break down protein to peptides
• D. protect the stomach lining

Answer 1

The correct option is C break down protein to peptides

Gastric juice is a unique combination of HCl, pepsinogen, lipase, and mucus.

HCl helps to activate the inactive pepsinogen to active pepsin.

Pepsin aids in digestion by breaking the bonds in protein into peptides.

Lipase helps to break fats.

Mucus protects the epithelial lining of the stomach from HCl.
