A student investigated the effect of temperature on the rate of aerobic respiration in yeast using the redox indicator DCPIP. Yeast suspensions were mixed with glucose and DCPIP and incubated at the temperatures shown in the table. The time taken for the DCPIP to become colourless was recorded.
| Temperature (°C) | Time for decolourisation (minutes) |
|---|---|
| 10 | 25 |
| 20 | 15 |
| 30 | 8 |
| 40 | 6 |

Outline the process of aerobic respiration, including the location of each stage, and use the data in the table to explain the effect of temperature on the rate of respiration.
