What mixes to form Pepsin in the stomach?

Explanation:
Pepsin is formed when the inactive enzyme precursor pepsinogen, secreted by stomach chief cells, meets the acidic environment created by hydrochloric acid from stomach parietal cells. The low pH of the gastric juice converts pepsinogen into the active enzyme pepsin. This activation is what allows pepsin to digest proteins in the stomach. Pepsinogen alone is inactive, and hydrochloric acid alone doesn’t produce pepsin; it’s the combination of the two in gastric juice that yields the active enzyme.
