Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
An enzyme works best at pH 8. The rate of reaction at pH 5 is much lower. Which statement best explains this difference?
- The enzyme has more kinetic energy at pH 5.
- The substrate is used up at pH 5.
- The active site is distorted at pH 5.
- The enzyme concentration is higher at pH 8.
