Study Guide: Cellular Respiration and Photosynthesis Test

1. What is the overall purpose of cellular respiration?

2. What is the advantage of the many folds in the membrane of mitochondria?

3. Do plants carry out cellular respiration? Why or why not? (Hint: look at #3 above.)

4. What can cells use for fuel other than carbohydrates? Gram for gram, do they contain more or less potential energy?

5. What are potential energy and kinetic energy? Which kind of energy is stored in glucose and ATP?

6. How do cells get the energy to make ATP? Where is ATP made?

7. Why do they bother to make ATP instead of just using a lot of glucose?

8. How do cells get energy out of ATP?

9. When might a cell use ATP (list 4 occasions)?

10. How do the reactants and products of cellular respiration (other than glucose) get into and out of cells?

11. What is the basic effect of all of the changes that come from athletic conditioning?

12. What is the difference between cellular respiration and anaerobic respiration? Why is cellular respiration (aerobic respiration) so much better than anaerobic respiration?

13. If it’s so much better, why do organisms have both? Isn’t that inefficient?

14. Why can muscles keep working a while without oxygen, but successful first aid demands restarting a heart

within 5 minutes?

15. What is the purpose of chlorophyll?

16. In what organisms is chlorophyll found? Where in those organisms will you find chlorophyll?

17. How many chloroplasts would you find in a green bush? Dozens? Hundreds? More than that?

18. What are 2 reasons why humans depend on plants in order to stay alive?

19. Fill out this chart.

20. What is the relationship between the equation for the overall photosynthesis reaction and the equation for cellular respiration reaction?

21. What are 2 things we get from the food we eat?

22. What are the 3 most common elements in living things? What are the next three?

23. If we are mostly made up of the same elements that make up cacti, how can we be so different?

24. Fill out this chart.

3 major classes of nutrients

Building blocks for each nutrient

25. The Calvin Cycle is part of __________________. (photosynthesis or cellular respiration?)

The Krebs Cycle is part of ___________________. (photosynthesis or cellular respiration?)

26. What is a stomate and what is its function?

Process reactants products In which cell organelle does the process take place?

Cell respiration (aerobic)

Fermentation (anaerobic respiration)

N/A

Photosynthesis
