Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
A student investigates how temperature affects the activity of an enzyme that works best at body temperature (37 °C). She measures the time taken for the same amount of substrate to be completely broken down at 10 °C, 37 °C and 70 °C.
At which temperature will the reaction be slowest?
At which temperature will the reaction be slowest?
- 70 °C
- 37 °C
- 10 °C
- The reaction is equally fast at all three temperatures.
