Functions of the Stomach in the Digestive System (In detail)
The role of acid in our stomach
Rennin enzyme produced in stomach
Pepsin enzyme produced in stomach
The stomach cells known as chief cells are responsible for the production of pepsin, an enzyme.
This enzyme digests the protein.
But keep in mind that the pepsin enzyme does not directly digest the protein, but HCl also contributes to this.
The pepsin enzyme works only in an acidic medium. HCl makes the food acidic and activates the pepsin enzyme.
The pepsin enzyme converts proteins into peptones, which are the simplest form of protein.
The stomach breaks down and mixes the food.
