Which of the following gastric secretions is correctly matched with its source?
Options
- APepsin Chief cells
- BChymotrypsin Parietal cells
- C Goblet cells
- DMucus Oxyntic cells
Correct answer
A. Pepsin Chief cells
Step-by-step solution
Parietal cells (or oxyntic cells) secrete hydrochloric acid and Castle's intrinsic factor. Chief cells (or peptic cells) secrete gastric digestive enzymes as proenzymes 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.
