Which enzyme helps in protein digestion in the stomach?
Answer and explanation
Correct answer: Pepsin
The governing concept is digestion of different nutrients by specific enzymes. In the stomach, hydrochloric acid provides an acidic medium that activates pepsin. Pepsin begins breaking large protein molecules into smaller peptides, so option A is correct. Amylase acts mainly on starch in the mouth and small intestine, lactase digests lactose in the small intestine, and chlorophyll is a photosynthetic pigment rather than a digestive enzyme.
