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

  1. A
    Enterokinase will not be released from the duodenal mucosa.
  2. B
    Gastric juice will be deficient in chymosin.
  3. C
    Gastric juice will be deficient in pepsinogen.
  4. D
    In the absence of secretion, inactive pepsinogen is not converted into the active enzyme pepsin.

Solution & Step-by-step Explanation

Parietal (oxyntic) cells secrete hydrochloric acid (). is essential for maintaining an acidic in the stomach, which triggers the conversion of the proenzyme pepsinogen into its active form, pepsin. Without , protein digestion is severely impaired.
