Quizplus · Accepted Answer

Enzymes are highly sensitive to their environment, and their activity can be significantly affected by pH. The stomach has a highly acidic environment (low pH), while the small intestine is less acidic (higher pH). This difference in pH can cause an enzyme that is active in the stomach to become inactive in the small intestine because the enzyme's shape, which is crucial for its function, can be altered by the pH change.
