WebPepsinogen is an inactive enzyme (zymogen) that is released by chief cells into the stomach lumen. In order to be activated, the enzyme must be at a very low pH. This is accomplished by hydrochloric acid, which is released by the parietal cells in response to stimulation by gastrin. WebPepsinogen is a precursor of pepsin stored in the stomach walls. It is converted into pepsin by hydrochloric acid. It is the activated in the form of pepsinogen. Pepsinogen ------ …
