Method
Enzyme Activity Experiment
In this experiment, the effect of temperature on enzyme activity is investigated. A solution containing enzyme and substrate is prepared. The temperature is varied, and the rate of reaction is measured by the amount of product formed over time.
| Temperature (°C) | Rate of Reaction (units) |
|---|---|
| 20 | 5 |
| 30 | 10 |
| 40 | 15 |
| 50 | 8 |
| 60 | 2 |
