Study Notes
Energy Released During Respiration
- The energy released during respiration is utilized to fuel various processes in the human body.
Measuring Rate of Respiration
- The time taken for methylene blue to change color can be converted into a measure of the 'rate of respiration'.
- This rate can be plotted on a graph to visualize the relationship between the variables.
- Note that a graph of temperature against 'time for color change' would have a different appearance compared to the graph shown.
