A student investigated the effect of temperature on the rate of aerobic respiration in yeast using DCPIP as a redox indicator. Yeast suspensions were mixed with DCPIP at different temperatures and the time taken for the DCPIP to become colourless was recorded. The results are shown in the table.
| Temperature / °C | Time for DCPIP to become colourless / minutes |
|---|---|
| 10 | 18 |
| 20 | 10 |
| 30 | 6 |
| 40 | 4 |
| 50 | 8 |
| 60 | 12 |
