Investigating Respiration Rate
We can measure the rate of respiration in living organisms like seeds or small insects using a respirometer.
How does a respirometer measure oxygen uptake?
What is Investigating Respiration Rate?
"The respiration practical uses a respirometer to quantify the oxygen consumption of living organisms over time."
Anaerobic respiration in yeast is also called:

Why is fermentation economically important?
Respirometer Setup
Soda lime is used to absorb the carbon dioxide produced.
As oxygen is consumed, the pressure drops and dye moves along a tube.
The distance moved indicates the volume of oxygen used.
Temperature must be controlled because respiration is an enzyme-controlled process.
