Could you please describe and explain the link between oxygen concentration, rate of respiration and rate of uptake of potassium ions.
This is in relation to a table with the description that discs of carrot were placed in a solution containing potassium ions (K+).
The concentration of oxygen in air bubbled through the solution and was changed and the rates of respiration and uptake of potassium ions were measured.
The results are below.
| Concentration of oxygen |
Rate of Respiration/Arbitrary Units |
Rate of uptake of Potassium Ions/Arbitrary units |
| 2.7 |

| 12.2 |
