Which cells secrete pepsinogen, the inactive form of pepsin, in the stomach?

Explanation:
Chief cells in the stomach's gastric glands secrete pepsinogen, the inactive precursor to pepsin. This zymogen form protects the stomach lining from being digested. In the acidic environment created by parietal cells (which release HCl), pepsinogen is activated to pepsin, the enzyme that begins protein digestion. Goblet cells produce mucus to shield the stomach lining, parietal cells secrete acid and intrinsic factor, and salivary amylase comes from the salivary glands and works in the mouth, not in the stomach.
