1.
Circle the words below that apply to the process of photosynthesis and explain why it applies.
Not all the words will apply.
catabolic, anabolic, endothermic, exothermic, mitochondria, chloroplasts
chemiosis, electron transport chain, enzymes
Explain:
1.
2.
3.
2.
Write the chemical equation that applies to the whole process of photosynthesis.
3.
List the two parts of the process of photosynthesis?
4.
What parts of a plant is specialized for photosynthesis?
5.
Draw and label the chloroplasts (smooth membrane, thylakoid, granum, stroma). Color the area
where the light reaction is occurring pink. Color the area where the calvin cycle is occurring blue.
Also label where the CF1 particle would be.
6.
What are the main events that occur in the light reaction?

What are three ways to reduce and oxidize compounds and what happens to their energy content
during each process.
OXIDATION
1.
2.
3.
REDUCTION

2.
3.
8.
Explain what happens in chemiosmosis?
9.
Explain what happens in the electron transport chain?
10. What is the ultimate electron acceptor at the end of the electron transport chain?
11. Why is light and chlorophyll needed in the light reaction?
12. Draw and label the parts of a ATP molecule. How is ATP made?
13. How is NADP converted to NADPH in the light reaction?
14. Where does the Calvin cycle occur?
15. List two types of chemical energy that is made in the light reaction that is needed for the Calvin
cycle?
Fill in the chart below:
Molecule made
PGAL
Glucose
# ATP needed
# NADPH (NADPre)
# CO2
16. What is the end product of Calvin?
17. How is glucose made if it is not the end product?
18. List four other molecules that can be made from PGAL and how are they made?
19. What are the two types of chlorophyll found in higher plants?
20. What are the other accessory pigments found in higher plants?
21. What type of light is most effective for photosynthesis and least effective for photosynthesis?
22. Why can photosynthesis still occur in green light?
23. What is photorespiration? Draw a graph representing photorespiration (x-time , y-rate of
photosynthesis) What is the ratio of gasses needed for photorespiration to occur? __________
24. Under what condition would the above mentioned ratio of gases be established in a plant?
Draw the anatomy of a C3 and a C4 leaf and point out their differences.
C3
C4
25. Why is a C4 plant more efficient at photosynthesis than a C3 plant that is under water stress?
26. How is C4 photosynthesis different from C3 photosynthesis?
27. What is CAM photosynthesis?
