Cellular respiration Review:
1. Why is ATP the “energy currency” of the cell?
2. Why is ATP so unstable?
3. If ATP is so unstable, then doesn’t that make it a bad choice for energy storage?
4. Draw and label a basic ATP.
5. True or False: The main idea of cellular respiration is that energy found in the electrons from the
food we eat can be transferred through a series of “step- down” redox reactions to eventually be
used to join ATP +Pi yielding ATP.

What is the difference between chemiosmosis and ETC?
What is a “proton motive force”?
What are the 2 types/ levels of ATP creation? Star the one that requires MORE energy to do.
What term means to ‘add a phosphate” to something?
Using glycolysis, give a specific example of energy coupling.
If pyruvate has 3 carbons, oxaloacetate has 4 carbons and citric acid has 6 carbons (Co-enzyme A
has a ton of them, 21, but is not relevant here) what does that tell you must happen between the
last compound made (oxa, for short)? (see diagram below)
13. Why do I say that the number of carbons in co-enzyme a, (Co-A for short) is not relevant? (Hint,
think about enzymes)
14. Complete this sentence: Breaking __________ bonds in _____________ to create chemical bonds in
___________ is the ultimate goal of cellular respiration.
15. Using the diagram below and your knowledge, put these compounds in order they are produced:
Pyruvate, Co-A, Oxaloacetate, Acetyl-Co A, Citric Acid, PGAL, and Glucose.
16. Write the formula for the more expensive, but efficient carrier when it is reduced.
17. What is the difference between a compound/molecule that has been oxidized and one that has
been reduced?
18. List any/all waste products of cellular respiration.
19. How are the items you identified above dealt with?
20. What evidence is there to confirm that we are aerobic creatures in our cell processes?
21. Using the diagram below to help you, what is another name for citrate?
22. Based on what you said above, what is another name for pyruvic acid?
23. Again, check out that fabulous diagram below and give me the name of any ONE enzyme used in
this stage of cellular respiration.
24. Why is FAD “better” than NAD? (Be specific)
25. Why don’t we just use FAD then?
26. Notice “GTP” provide a logical answer for what you think that is.
27. Write out (seriously) ALL questions you have! We will address them before lab on Monday!
