Effect of temperature and pH on enzymes
Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
An enzyme-controlled reaction is carried out at pH 7 and 37 °C. The mixture is then heated to 80 °C for 5 minutes and cooled back to 37 °C, while pH remains 7.
What will happen to the rate of reaction after cooling?
What will happen to the rate of reaction after cooling?
- It returns to the original rate.
- It becomes slightly faster than before.
- It becomes slower and then slowly returns to normal.
- It stays very low because the enzyme is denatured.
