| Front | How does a respirometer work? |
|---|---|
| Back | - O2 absorbed by organism in aerobic respiration - CO2 produced absorbed by KOH - volume of gas in tube decreases - pressure in tube decreases - liquid in capillary tube moves towards test tube down pressure gradient - distance moved * diameter of capillary tube = volume O2 absorbed - rate of O2 absorption is proportional to rate of aerobic respiration |
