Process of Digestion: In Stomach -

 
  • The stomach stores food for 4-5 hours. 
  • The food mixes thoroughly with the acidic gastric juice in the stomach by the churning movements of its muscular wall and is called the chyme.
  • The proenzyme pepsinogen, on exposure to hydrochloric acid, gets converted into the active enzyme pepsin, the proteolytic enzymes of the stomach. 
  • Pepsin converts proteins into proteases and peptones (peptides). 
  • The mucus and bicarbonates present in the gastric juice play an important role in lubrication and protection of the mucosal epithelium from excoriation by the highly concentrated hydrochloric acid. 
  • HCl provides the acidic pH (pH 1.8) optimal for pepsin. 
  • Rennin is a proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins. 
  • Small amounts of lipases are also secreted by gastric glands.

The proenzyme pepsinogen, on exposure to hydrochloric acid gets converted into the active enzyme pepsin, the proteolytic enzymes of the stomach. Pepsin converts proteins into proteoses and peptones (peptides). Hence, the correct answer is option c.
