Explanation:
* A gastric chief cell (or peptic cell or gastric zymogenic cell) is a cell in the stomach that releases pepsinogen and gastric lipase and is the cell responsible for secretion of chymosin in ruminants.
Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.
