Digestion And Absorption Question 47
Question: What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?
Options:
A) Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted into trypsin.
B) Gastric juice will be deficient in chymosin.
C) Gastric juice will be deficient in pepsinogen.
D) In the absence of HC1 secretion, inactive pepsinogen is not converted into the active enzyme pepsin.
