Q. What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?
A) Gastric juice will be deficient in chymosin
B) Gastric juice will be deficient in pepsinogen
C) In the absence of HCl secretion, inactive pepsinogen is not converted into the active enzyme pepsin
D) Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin
Explanation
The oxyntic cells or parietal cells of the gastric glands secrete HCl. This HCl converts pepsinogen and prorennin to pepsin and rennin respectively.
