Answer:
The optimal temperature for sucrase activity is higher than body temperature
Explanation:
The optimal temperature for sucrase activity is 40 °C. That means the activity decreases both when the temperature is higher than 40 °C and when it is lower.
Body temperature is 37 °C, so the enzyme is working at less than maximum efficiency.
If your body temperature drops, the sucrase activity will decrease. If you get a fever, the activity will increase.
