              CELL RESPIRATION PRE-LAB WORKSHEET



1) Mitochondria; Refer to page 96 of Raven & Johnson.

     A) Label the following structures of the mitochondria:
           Matrix, Cristae, Outer compartment, Outer membrane,
           Intermembrane space.

     B) Describe what is embedded in the inner membrane.



     C) Where does citric acid cycle occur?



     D) Where does oxidative respiration occur?



     E) Describe characteristics of the mitochondria that seemingly make them autonomous organelles.




     F) Explain why they are not completely autonomous.




3) AP Lab: Cellular Respiration

     A) Write the complete equation for cellular respiration. Include how much energy is released per mole of
        glucose. Is this a balanced equation?




     B) Describe the three ways in which cellular respiration could be measured. Identify which way we will
        use.
C) Diagram the apparatus that will be used to measure the rate of cellular respiration. Label the materials
   that will be placed in the tube.

D) Describe the role of the following materials or substances.

       KOH:



       Glass beads:




       Absorbent cotton:



       Non-absorbent cotton:



E) Explain how you will measure the respiration rate of the peas.




F) Explain how you determine the corrected difference in the “germinating peas” column.




G) Why must you use a corrected difference?




H) Identify the independent and dependent variable in this lab.




I) Several gas laws effect the apparatus used in this lab. Write the general gas law formula. Circle the
   independent variable for this lab.



J) Explain what the rest of the formula stands for and what two factors will change the reading not
   related to the cellular respiration carried on by the peas.
