10 Questions
How can the 'rate of respiration' be determined using methylene blue?
By measuring the time taken for the colour to change
What is the main use of the energy released during respiration in the human body?
To fuel muscle contraction and nerve impulse transmission
What would the graph of temperature against 'time for colour change' look like compared to the graph of 'rate of respiration' against 'time for colour change'?
The graph of temperature would be completely different
What is the term for the process that converts the energy stored in organic compounds into a usable form for the body?
Respiration
Which of the following processes does NOT use energy released during respiration?
Photosynthesis
The energy released during respiration is not utilized in any processes in the human body.
False
Methylene blue can be used to determine the rate of photosynthesis in plants.
False
A graph of temperature against 'time for colour change' will look the same as the graph used to plot 'rate of respiration' against 'time for colour change.'
False
The energy released during respiration is only utilized for a single process in the human body.
False
The 'rate of respiration' can be directly determined by observing the color change of methylene blue over time.
True
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.
Test your knowledge on the measurement of respiration rate in humans using methylene blue. Learn how the energy released during respiration fuels various processes in the human body. Understand the process of converting time for colour change into 'rate of respiration' and analyzing the results through graph plotting.
