Cellular Respiration Lab Questions
1. As a cricket, you feel that your kind is being misrepresented in this lab. Playing the role
of the cricket…
A) explain why the raw data is an inaccurate comparison between organisms, and
B) adjust the raw data so that a fair comparison can be made (submit a copy of your
adjusted data),
Graph 1 – Print out a single, properly labeled graph that shows adjusted cumulative CO2
production of all three organisms at room temperature using class data.
2. What is the rate of CO2 production for each of the three organisms at room
temperature (using your adjusted data)?
Graph 2 – Print out a second, properly labeled graph that shows adjusted cumulative CO2
production of just the crickets at low and room temperature using class data.
3. What is the rate of CO2 production for the crickets at low and room temperature (using
your adjusted data)?
4. Explain why there are differences in the data between...
A) germinating and dry peas
B) crickets at low and room temperature
5. During aerobic cellular respiration, glucose is broken down.
A) Which end products contain the carbon atoms from glucose?
B) Which end products contain the hydrogen atoms from glucose?
C) Which end products contain the oxygen atoms from glucose?
6. How might the data be different if we used a mouse as another test subject? How
would its rate of CO2 production at room temperature compare to the crickets? How
would its CO2 production vary with temperature?
