    Since pepsin is an enzyme, it will digest protein in stomach cells along with the food. Therefore, to prevent this, the body was designed to produce the protein as an inactive zymogen, pepsinogen. In this form, pepsinogen cannot digest the proteins in the "chief cells" of the stomach that produce it. Therefore, it does not become active until it comes into contact with another active pepsin molecule and HCl produced by the parietal cells of the stomach. It does not become active until it arrives at the location ...
