Which enzyme helps in protein digestion in the stomach?
Answer and explanation
Correct answer: Pepsin
Pepsin is the principal enzyme that begins protein digestion in the stomach. Hydrochloric acid provides the acidic medium that activates pepsin from its inactive form and supports its action on proteins, producing smaller peptide molecules. Amylase digests starch, while maltase and sucrase act on sugars mainly in the small intestine. Hence, option A is correct.
