Introduction:

The digestive system breaks down the food so that nutrients can be absorbed by the body. There are three primary functions of the digestive system. The digestive system absorbs food, breaks it down so that nutrients can be absorbed and removes that cannot be digested.

Explanation of Solution

Glucose is a subcategory of carbohydrates and glycogen is a polysaccharide of glucose. They are not enzymes. Pepsin is the chief digestive enzymes in the stomach that breaks down proteins into polypeptides. The acidic environment in the stomach is favorable to the action of pepsin. Pepsin is an endopeptidase which breaks down the proteins into smaller peptides. It is generated in the main cells of the lining of the stomach and an important digestive enzyme.

Conclusion

Thus, pepsin breaks down proteins into smaller peptides and it is generated in the main cells of the lining of the stomach. It is an important digestive enzyme.
