A plant cell culture is supplied with glucose in a sealed container with no oxygen.
The table shows the volume of carbon dioxide produced in consecutive 5-minute intervals.
| Time interval in minutes | Volume of carbon dioxide produced in cm³ |
|---|---|
| 0–5 | 3.2 |
| 5–10 | 4.0 |
| 10–15 | 4.8 |
| 15–20 | 4.0 |
Calculate the mean rate of carbon dioxide production during the 20 minutes.
Give your answer in cm³ per minute.
Name the other product of respiration in this culture.
Explain why this type of respiration transfers less energy from each glucose molecule than aerobic respiration.
