Verified step by step guidance1
Understand that gastric juice is a digestive fluid produced in the stomach, essential for breaking down food.
Identify the three main components of gastric juice: Hydrochloric acid (HCl), pepsin, and mucus.
Hydrochloric acid (HCl) creates an acidic environment in the stomach, which is necessary for the activation of pepsinogen to pepsin and for killing bacteria.
Pepsin is an enzyme that breaks down proteins into smaller peptides, and it is activated from its inactive form, pepsinogen, by the acidic environment.
Mucus serves as a protective layer that lines the stomach, preventing the stomach lining from being digested by the acidic environment and enzymes.
