Answer
The substance contained in gastric juice is: Hydrochloric acid, enzyme pepsin, and mucus. These substances perform the following functions:
Hydrochloric acid: It creates a medium of gastric juice acidic so that the enzyme pepsin digests the protein and kills the bacteria present in them.
Pepsin: The enzyme pepsin digests the protein and breaks down into smaller molecules.
Mucus: The mucus helps to protect the inner layer of the stomach from the secretion of hydrochloric acid.
