Which cells secrete pepsinogen?

Explanation:
Pepsinogen is the inactive precursor of the digestive enzyme pepsin, and it is produced by the stomach’s chief cells (also called peptic or zymogenic cells). These cells reside in the gastric glands of the stomach and specialize in secreting protein-digesting enzymes in their zymogen form to protect the gland tissue from being digested. When pepsinogen enters the stomach’s acidic environment created by parietal cells, it is activated into pepsin, which then begins protein digestion. In contrast, parietal cells secrete hydrochloric acid and intrinsic factor, G cells release gastrin, and goblet cells produce mucus—none of which directly secrete pepsinogen.
