Explanation
Zymogen cells, also known as chief cells, secrete pepsinogen and chymosin. Pepsinogen is an inactive form of pepsin, which is an enzyme that breaks down proteins. Chymosin is an enzyme that curdles milk. Both pepsinogen and chymosin are stored in the stomach in an inactive form. When they come into contact with hydrochloric acid, they are activated and begin to digest food.
