Pepsin is produced as the inactive zymogen pepsinogen by the zymogen (chief) cells of the stomach lining.

Pepsinogen is an inactive proenzyme. It is converted into the active enzyme pepsin by the acidic environment created by hydrochloric acid (HCl) in the stomach.

Rennin is the enzyme responsible for the coagulation of milk protein, specifically acting on caseinogen to form casein.

Pepsin is a digestive protease that is secreted and functions specifically within the stomach.

The gastric juice in the stomach is highly acidic due to the secretion of hydrochloric acid, typically maintaining a pH range between 1.5 and 3.0.

Pepsin is the enzyme secreted by the stomach wall that acts on proteins, such as casein, to begin the digestive process.

Gastric juice contains hydrochloric acid, giving it a very low pH (highly acidic) compared to saliva, bile, or pancreatic juice, which are neutral or alkaline.
