Study Guide for Photosynthesis vs. Cell Respiration Quiz
1. What is an autotroph? Give an example.
An organism that can make it’s own food. An example is a plant.
2. When is energy released from ATP?
When the phosphate / “P” is removed from ATP
3. In the process of photosynthesis, sunlight converts water & carbon dioxide into
what?
Oxygen & Glucose ( a high energy sugar)
4. How do plants gather the sun’s energy?
With their pigments
5. What are organisms that cannot make their own food & must obtain energy from the
foods they eat called?
Heterotrophs
6. What is the Calvin Cycle also called?
Light Independent Reactions
7. What are the reactants in the equation for cell respiration?
Oxygen (O2) & glucose (C6H12O6)
8. What is one cause of muscle soreness?
Lactic Acid Fermentation
9. What process is used to make beer & wine?
Alcoholic Fermentation
10. What is your body doing when you breathe heavily after running a race?
Repaying an oxygen debt
11. Photosynthesis: chloroplasts
Cell respiration: _mitochondria_
12. Cell respiration releases energy by breaking down what?
food
13. What are the products of cell respiration?
Water (H2O), Carbon Dioxide (CO2) and Glucose (C6H12O6)
14. In the presence of oxygen, what process follows glycolysis?
Kreb’s Citric Acid Cycle
15. Why is cellular respiration called an aerobic process?
Because it requires oxygen
16. What is the starting molecule for cell respiration?
Glucose
17. How do the products of photosynthesis compare to cell respiration?
The products of photosynthesis are the reactants of cell respiration
18. What is the order of events during cell respiration if there is oxygen?
Glycolysis  Kreb’s Citric Acid Cycle  Electron Transport Chain
19. What is the equation for cell respiration?
6O2 + C6H12O6  6H2O + 6CO2 + 36ATP
20. How do the reactants of photosynthesis compare to cell respiration?
The reactants of photosynthesis are the products of cell respiration
21. What is the equation for photosynthesis?
6H2O + 6CO2 + energy (sunlight)  6O2 + C6H12O6
22. Why is fermentation called anaerobic?
Because it does not require/use oxygen
23. Which type of respiration (aerobic or anaerobic) produces the most energy?
Aerobic
24. What are the products for cell respiration? (words)
Carbon Dioxide, Water & energy
