Pepsin is a hydrolytic enzyme found in the cell. How does pepsin prevent destroying the cells in the stomach which produce this enzyme?

Correct Answer: B. Pepsin remains in an inactive state until it is cleaved by HCl.
Pepsin along with many other hydrolytic enzymes are produced in a “zymogen” form which remain inactive during their production. Once they are in the correct conditions, they self cleave and become active. Pepsin is secreted in the inactive form known as pepsinogen, which is cleaved in the acidic conditions of the stomach to form the active protease pepsin.
