RESPIRATION QUESTIONS
Name: __________________________
Read pages 146-152 to answer the following questions.
1. Identify the two reactants and three products of cellular respiration.
2. What is cellular respirations main function?
3. Which of the following atoms attracts electrons the most: hydrogen, carbon, or
oxygen?
4. What happens as electrons “fall” from the carbon and hydrogen in glucose to
oxygen? What is the energy that is released used for?
5. What is the role of electron carriers in the slow release of energy during
cellular respiration?
6. Draw and label the structure of a mitochondrion. How is the inner membrane
different than the outer membrane? Why is this imporant?
7. Identify the three stages of cellular respiration.
8. What does glycolysis mean? Where does this reaction take place?
9. What carbon molecule is produce from glucose during glycolysis? What
electron carrier and energy molecules are produced during this reaction?
10. Before the Kreb’s cycle begins, what happens to the pyruvic acid created in
glycolysis? What gas is given off in the process? Are electron carrier or
energy molecules produced? Explain.
11. What happens to the two carbons in the acetyl Co-A molecule that enter the
Kreb’s cycle? Are electron carrier or energy molecules produced? Explain.
12. What happens next to the electrons being carried by the NADH and FADH2
molecules? How is this process similar and different than what goes on in
photosynthesis?
13. What happens to the electrons at the end of the electron transport chain?
How is this reminiscent of photosynthesis?
14. What is the final step in cellular respiration? How is similar and different to
the same process in photosynthesis?
