Biology · Secondary 3 · Hard · Effect of temperature and pH on enzymes
A student investigates how temperature affects the activity of the enzyme catalase on hydrogen peroxide. She measures the volume of oxygen produced in 1 minute at different temperatures. At 37°C, the volume is highest. What is the most likely result at 70°C?
- The same volume of oxygen as at 37°C
- A slightly higher volume of oxygen than at 37°C
- A much lower volume of oxygen than at 37°C
- No oxygen at any temperature including 37°C
