A genetic mutation prevents the parietal cells of the gastric glands from secreting their typical products. What effect would this have on digestion within the stomach?
A)The stomach would not produce a protective mucus coating and would digest itself.
B)Somatostatin would be secreted, so all digestion would be halted.
C)Pepsinogen would not be secreted, so protein digestion would not occur within the stomach.
D)Hydrochloric acid would not be produced, so pepsinogen would not be activated to form pepsin.

Parietal cells are responsible for producing hydrochloric acid, which creates an acidic environment necessary for the activation of pepsinogen into pepsin, the enzyme responsible for protein digestion in the stomach. Without the production of hydrochloric acid, pepsinogen would not be activated, and protein digestion would not occur in the stomach.
