Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
A student investigates the effect of temperature on an enzyme that breaks down starch. She measures the time taken for the starch to be completely digested at different temperatures. Her results are:
20°C: 6 min
30°C: 3 min
40°C: 1 min
60°C: no digestion after 10 min
At which temperature is the rate of reaction the highest?
20°C: 6 min
30°C: 3 min
40°C: 1 min
60°C: no digestion after 10 min
At which temperature is the rate of reaction the highest?
- 20°C
- 30°C
- 40°C
- 60°C
