Effect of temperature and pH on enzymes
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. She measures the time taken for a cloudy mixture to become clear at different temperatures.
At 20°C the mixture clears in 80 s. At 30°C it clears in 40 s.
What happens to the rate of reaction when the temperature is increased from 20°C to 30°C?
At 20°C the mixture clears in 80 s. At 30°C it clears in 40 s.
What happens to the rate of reaction when the temperature is increased from 20°C to 30°C?
- It doubles.
- It halves.
- It increases by 40 units.
- It stays the same.
