The secretion of pepsinogen and hydrogen ions are inversely related; as acid secretion increases, pepsinogen decreases.

Question

Quizplus · Accepted Answer

Pepsinogen secretion by chief cells and hydrogen ion (HCl) secretion by parietal cells in the stomach are not inversely related; both are stimulated during the gastric phase to aid in digestion, with HCl providing the acidic environment necessary for pepsinogen to be converted into its active form, pepsin.
