Effect of temperature and pH on enzymes
Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
The rate of an enzyme‑controlled reaction is highest at 37 °C. What happens to the rate when the temperature is increased to 60 °C, and why?
- Rate increases because particles move faster.
- Rate stays the same because temperature has no effect.
- Rate decreases because the enzyme becomes denatured.
- Rate decreases because the substrate is destroyed by heat, not the enzyme.
