Effect of temperature and pH on enzymes
Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
In an experiment, pepsin digests protein fastest at about 37 °C. What happens to pepsin activity when the temperature is raised to 70 °C?
- Its activity decreases sharply because the enzyme becomes denatured.
- Its activity keeps increasing because particles move faster.
- Its activity stays the same because enzymes are unchanged by heat.
- Its activity decreases slightly but the enzyme does not denature.
