Biology 10 - General Biology Lecture 10 Cellular Respiration • How ...

Study Questions :
1. What do organisms do with the glucose they either make (like plants) or ingest (like us)?
2. What is the only usable molecular form of energy within the cell?
3. What multi-step set of reactions do cells use to interconvert nutrients (ie glucose) and ATP?
4. What is the overall simplified cellular respiration reaction? What is the overall goal of cellular respiration? How
does it relate to photosynthesis?
5. Can cells store ATP? Does cellular respiration need to occur constantly in a living organism? How do you
know this to be true (hint : think of the need for oxygen by living organisms)
6. What is the basal metabolic rate? Approximately how many calories is the average human basal metabolic
rate?
7. What can you do to increase the amount of calories you are using during the day?
8. What are the two methods or strategies of cellular respiration? Which method of respiration is more effective at
capturing the energy in the bonds of ATP?
9. Where does the carbon dioxide that we exhale come from?
10. What molecule must be present for aerobic cellular respiration to occur?
11. How efficient is aerobic cellular respiration at capturing the energy in glucose into the energy in the bonds of
ATP (How many ATP are made)? How efficient is anaerobic cellular respiration at capturing the energy? In what
form is most of the energy “lost”?
12. What is lactic acid? When is lactic acid formed? What are some of the problems with lactic acid and ethanol?
What is the advantage of anaerobic cellular respiration?
13. Where does anaerobic cellular respiration occur?
14. Where does aerobic cellular respiration occur?
15. Can cells use organic molecules other than glucose for energy? Which organic molecules require oxygen to be
used? Which organic molecule can be used anaerobically?
16. What are the three reaction of aerobic cellular respiration?
17. How is oxygen used in the electron transport chain? What does oxygen form when it combines with the
electrons and hydrogen?
18. Why is it important that we breathe oxygen? Why do cells die very quickly when oxygen is not present?
19. Which organic molecule contains the greatest amount of energy per gram?
20. If you wanted to loose weight by specifically burning fat would it be best to run or walk? Why?
21. Describe the relationship between photosynthesis and cellular respiration. (look at the above diagram)
