What happens when a protein-digesting enzyme functions in an acidic medium?

A protein-digesting enzyme like pepsin functions best in an acidic medium, such as the pH found in the stomach (around 1.5 to 2). This acidic environment helps maintain the enzyme’s optimal structure, enabling it to break down proteins efficiently.
