Effect of temperature and pH on enzymes
Biology · Secondary 3 · Hard · Effect of temperature and pH on enzymes
A student investigates how temperature affects the rate of an enzyme-catalysed reaction. She measures the volume of oxygen released in 1 minute at different temperatures.
At 30°C, 20 cm³ of oxygen is released in 1 minute.
At 40°C, 40 cm³ of oxygen is released in 1 minute.
What happens to the rate of reaction when the temperature is increased from 30°C to 40°C?
At 30°C, 20 cm³ of oxygen is released in 1 minute.
At 40°C, 40 cm³ of oxygen is released in 1 minute.
What happens to the rate of reaction when the temperature is increased from 30°C to 40°C?
- It doubles.
- It halves.
- It increases by 10 cm³/min.
- It does not change.
