An investigation was carried out to study the effect of the quantity of immobilized amylase on the rate of starch digestion. Different numbers of alginate beads containing amylase were added to starch solutions, and the time taken for starch to be completely broken down was recorded.
The results are shown in the table below.
| Number of alginate beads containing amylase | Time taken for starch to be completely broken down / seconds |
|---|---|
| 5 | 360 |
| 10 | 180 |
| 15 | 120 |
| 20 | 90 |
Explain the conclusion that can be made from these results.
