What is the importance of an acidic medium in the stomach for digestion?
Answer and explanation
Correct answer: It helps the protein-digesting enzyme to work
The stomach secretes hydrochloric acid, which creates a strongly acidic medium. This medium helps activate pepsin from its inactive precursor and provides suitable conditions for pepsin to digest proteins into smaller peptides. The acid also helps destroy many microbes entering with food, although the enzyme-supporting role answers the question directly. Therefore option A is correct; the other options describe unrelated plant or excretory processes.
