Answer briefly: How does pepsinogen change into its active form?
(N/A) Pepsinogen is an inactive proenzyme (zymogen) secreted by the chief cells of the gastric glands in the stomach. It is converted into its active form,pepsin,by the action of hydrochloric acid $(HCl)$. The reaction is as follows:
$\text{Pepsinogen (Inactive)} \xrightarrow{HCl} \text{Pepsin (Active)} + \text{Inactive peptide}$
$\text{Pepsinogen (Inactive)} \xrightarrow{HCl} \text{Pepsin (Active)} + \text{Inactive peptide}$
