Biology · Secondary 4 · Hard · Effect of temperature and pH on enzymes
A student investigates the effect of temperature on the rate of an enzyme-catalysed reaction. At 30 °C, the time taken to produce a fixed volume of product is 40 s. At 40 °C, the time taken is 20 s.
What happens to the rate of reaction when the temperature is increased from 30 °C to 40 °C?
Use rate = .
