Biology · Secondary 4 · Hard · Effect of temperature and pH on enzymes
A student investigates the effect of temperature on the rate of an enzyme-controlled reaction. She measures the time taken for the same amount of product to form at different temperatures. At 20°C the time taken is 80 s, and at 40°C it is 20 s. How has the rate of reaction changed at 40°C compared to 20°C?
- It is 2 times faster at 40°C.
- It is 3 times faster at 40°C.
- It is 4 times faster at 40°C.
- It is 5 times faster at 40°C.
