Which of the following gastric secretions is correctly matched with its source?
Pepsin - Chief cells
Chymotrypsin - Parietal cells
HCl - Goblet cells
Mucus - Oxyntic cells
A.
Pepsin - Chief cells
Parietal cells (or oxyntic cells) secrete hydrochloric acid (HCl) and Castle's intrinsic factor.
Chief cells (or peptic cells) secrete gastric digestive enzymes as proenzymes such as pepsinogen and prorennin.
HCl helps in converting pepsinogen to pepsin.
Goblet cells secrete mucus which helps to neutralise acid in stomach and protects stomach wall against HCl action.
Assertion: HCl converts pepsinogen into active enzyme pepsin.
Reason: Pepsin converts protein into proteoses and peptones.
