An investigation was carried out to study the effect of temperature on the rate of starch digestion by amylase. The results are shown in the table below.
| Temperature of starch-amylase mixture in °C | Time taken for starch to be completely broken down in seconds |
|---|---|
| 20 | 185 |
| 30 | 110 |
| 40 | 55 |
| 50 | 140 |
Explain why the time taken for the starch to be completely broken down decreases as the temperature increases from 20°C to 40°C.
