Which cells secrete pepsinogen in the stomach?

Explanation:
Pepsinogen secretion is produced by the cells of the gastric glands called chief cells. They release the inactive enzyme precursor pepsinogen into the stomach lumen. When it meets the acidic environment created mainly by neighboring parietal cells, pepsinogen is activated to pepsin, an enzyme that digests proteins. Parietal cells produce acid and intrinsic factor; goblet cells secrete mucus to protect the lining; enterocytes line the small intestine and handle absorption. So, chief cells are the ones responsible for pepsinogen secretion.
