Study Notes
Energy and Respiration
- Energy released during respiration is used to fuel many processes in the human body.
Measuring Respiration Rate
- Time taken for methylene blue to change colour can be converted into 'rate of respiration'.
- The rate of respiration can be plotted on a graph.
- A graph of temperature against 'time for colour change' will have a different shape than the graph of rate of respiration.
