What part of the digestive system releases pepsin?

Explanation:
Pepsin is the protein-digesting enzyme that starts working in the stomach. It is released by the stomach’s chief cells as pepsinogen, a non-active precursor, and the highly acidic environment of the stomach converts pepsinogen into active pepsin. The stomach is the site where this enzyme is released and activated; the esophagus doesn’t secrete digestive enzymes, the small intestine relies on enzymes from the pancreas and intestinal lining, and the pancreas releases several enzymes but not pepsin. So the part that releases pepsin is the stomach.
