Effect of temperature and pH on enzymes
Biology · Secondary 3 · Hard · Effect of temperature and pH on enzymes
An enzyme that digests protein in the stomach works best at pH 2. Which statement predicts what happens if the pH is increased to pH 8 while temperature is kept constant?
- The enzyme activity decreases sharply because the enzyme is denatured.
- The enzyme activity increases because more collisions occur at higher pH.
- The enzyme activity stays the same because only temperature affects enzymes.
- The enzyme stops working only for a short time and then recovers fully.
