An investigation was carried out to study the effect of lactase concentration on the rate of lactose hydrolysis. The time taken for lactose to be completely broken down into glucose and galactose was recorded at different concentrations of the enzyme.
Table 1 shows the results of this investigation.
| Lactase concentration (%) | Time taken for lactose to be completely hydrolysed (seconds) |
|---|---|
| 0.5 | 240 |
| 1.0 | 110 |
| 1.5 | 60 |
| 2.0 | 35 |
| 2.5 | 25 |
Describe the trend shown in Table 1.
