Expert Answer:

Pepsin is a digestive enzyme found in gastric juice that catalyzes the breakdown of protein to peptides.

Gastric juice is the digestive secretion of the gastric glands in the stomach, consisting chiefly of pepsin, hydrochloric acid, rennin, and mucin.

Hydrochloric acid provides the acid environment in which pepsin is most effective. Rennin aids the digestion of milk proteins. Mucus secreted by the gastric glands helps protect the stomach lining from the action of gastric juice.
