Which among the following enzyme is responsible for the digestion of proteins in the small intestine ?

Trypsin

The correct answer is Option (3) –Trypsin

The pancreas secretes pancreatic juice which contains enzymes like trypsin for digesting proteins and lipase for breaking down emulsified fats.

The walls of the small intestine contain glands which secrete intestinal juice. The enzymes present in it finally convert the proteins to amino acids, complex carbohydrates into glucose and fats into fatty acids and glycerol.
