Effect of temperature and pH on enzymes
Biology · Secondary 4 · Hard · Effect of temperature and pH on enzymes
A student investigates how temperature affects the rate of an enzyme reaction. She measures the time taken for the same amount of product to form at different temperatures.
At 25 °C, it takes 40 s. At 35 °C, it takes 20 s.
Using the idea that rate is inversely proportional to time taken, what is the rate at 35 °C if the rate at 25 °C is 0.025 s⁻¹?
