Biology · Secondary 4 · Hard · Effect of temperature and pH on enzymes
A student investigates how temperature affects enzyme activity. She measures the time taken for an enzyme to completely break down its substrate at different temperatures.
At 30 °C, the reaction finishes in 80 s. At 40 °C, it finishes in 40 s.
What happens to the rate of reaction between 30 °C and 40 °C?
