Where is pepsin produced?

Explanation:
Pepsin is produced by the chief cells of the stomach’s gastric glands. They secrete pepsinogen, the inactive precursor, which is then activated to pepsin in the acidic environment created by hydrochloric acid from the parietal cells. Mucous cells produce protective mucus, and G cells release gastrin to stimulate acid secretion, but neither is responsible for secreting pepsin.
