1. Unit 3 Test Review
Trashketball

2. What is the purpose of photosynthesis?
Converting solar energy into chemical energy for storage

3. Light dependent reactions occur in what organelle?
Chloroplast of plant, algae, and some bacteria cells

4. Light dependent reactions occur in what part of the chloroplast?
Thylakoid membrane
Grana=stacks of thylakoids

5. The Calvin Cycle occurs in what part of the chloroplast?
The stroma
CO2 is fixed into sugar molecules in the stroma

6. What are the reactants in the light reaction of photosynthesis?
H2O, light, chlorophyll

7. What are the products of the light reaction of photosynthesis?
ATP, NADPH energy molecules
O2 is a by-product

8. What are the energy molecules ATP and NADPH used for?
Power for the Calvin Cycle

9. What are the reactants of the Calvin Cycle of photosynthesis?
ATP, NADPH, and CO2
RuBP and Rubisco help in making the product

10. What does the enzyme Rubisco do?
Converts RuBP and CO2 into G3P sugar molecules

11. Where does CO2 used in the Calvin Cycle come from?
Plants “breathe in” CO2 from the surrounding atmosphere via stomata
Stomata are tiny pores in leaves

12. What are the products of the Calvin Cycle of photosynthesis?
Sugars
to be consumed through cellular respiration in the plant/algae/bacteria
to be stored and passed down the food chain

13. What colors (wavelengths) do plants absorb for use in photosynthesis?
Red and blue

14. What colors (wavelengths) are reflected in plants?
green

15. Describe chemiosmosis in chloroplast.
H+ (hydrogen protons) are actively pumped in between thylakoid membranes
Proton concentration gradient is formed
Protons move by facilitated diffusion through ATP synthase

16. What is the purpose of cellular respiration?
Generating ATP for use in all cell processes
All living things can do cellular respiration!

17. What are the 3 major steps of cellular respiration?
Glycolysis
Kreb’s Cycle
E-transport chain

18. How much ATP is produced in each of the stages of cellular respiration?
Glycolysis– 2 ATP
Kreb’s Cycle—2 ATP
E-transport chain—32-34 ATP **most efficient

19. In what part of the mitochondrion does glycolysis, Kreb’s cycle, and e- transport chain occur?
Glycolysis- cytoplasm outside Mitochondrion
Kreb’s Cycle- inner mitochondrial space
E-transport chain- inner mitochondrial MEMBRANE

20. What are the two types of anaerobic respiration?
Alcohol fermentation
Lactic acid fermentation

21. What is produced during alcoholic fermentation?
ATP, alcohol, and CO2

22. What is the chemical equation for photosynthesis and respiration and how are they related?
6 CO2 + 6 H2O -> C6H12O6 +6O2
C6H12O6 +6O2 -> 6 CO2 + 6 H2O

23. Describe chemiosmosis in mitochondria.
H+ (hydrogen protons) are actively pumped in between mitochondrial membranes
Proton concentration gradient is formed
Protons move by facilitated diffusion through ATP synthase
