Question

Which of these statements about gastric secretion of HCl is false? (A) HCI hydrolyses peptide bonds (B) HCl is secreted by the parietal cells (C) HCl is needed for maximum activity of pepsin (D) HCl is needed for the conversion of pepsinogen to pepsin

Tardigrade Admin · Accepted Answer

The stomach contains gastric glands. These glands are made up of the different types of enzymes in which parietal cells secrete hydrochloric acid that creates an acidic pH in the stomach and aids in gastric motility. Also, HCl functions in the following ways in our stomach:

Hydrochloric acid is an important acid within the stomach.
It helps in destroying bacteria and also other harmful species.
It also works as a preservative of food.
HCl converts pepsinogen, which isn't active, into pepsin to metabolize proteins in our stomach.
HCl also acts as another stomach cover aside from mucus to avoid the pepsin from digesting the whole stomach.
