Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
Pepsin is a protease in the stomach. At 37 °C it digests proteins quickly. What happens to pepsin activity when the temperature is increased to 60 °C?
- Its activity decreases because the enzyme becomes denatured.
- Its activity keeps increasing because particles move faster.
- Its activity stays exactly the same as at 37 °C.
- Its activity stops only because all substrate is used up.
