• B. $HCl$
• C. trypsin
• D. renin

Answer 1

Answer: (B)

$HCl$

Answer 2

Oxyntic cells (= parietal cells) are large and are most numerous on the side walls of the gastric glands. They secrete hydrochloric acid and Castle�s intrinsic factor. Hydrochloric acid serves many functions like it kills harmful bacteria; it provides acidic medium in the stomach for gastric digestion; it changes pepsinogen into pepsin and prorennin into rennin; softens the food and make it readily available for enzyme action; it stops the action of salivary enzyme.
