What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?

Options

  1. AEnterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin
  2. BGastric juice will be deficient in chymosin
  3. CGastric juice will be deficient in pepsinogen
  4. DIn the absence of HCl\mathrm{HCl} secretion, inactive pepsinogen is not converted into the active enzyme pepsin.

Correct answer

D. In the absence of HCl\mathrm{HCl} secretion, inactive pepsinogen is not converted into the active enzyme pepsin.
