A.
The Reactions of Photosynthesis (pgs 208-214)
Inside a Chloroplast
1. Define thalakoid and stroma. Give their functions, and draw a small picture to
show each in a chloroplast.
2. Define photosystem: Give the 2 types and the 2 names for each one.
Include where each is located.
B.
Electron Carriers
1. What is a carrier molecule?
2. What is the process called when carriers are used?
3. Define NADP+.
4. What materials come into a chloroplast that are used in light-dependent reactions?
5. What materials come into the chloroplast that are used in the Calvin Cycle?
6. What materials move out of a chloroplast from the light-dependant reactions?
7. What moves out of chloroplast from the Calvin Cycle?
8. What materials move from the light-dependent reactions to the Calvin Cycle?
9. What materials move from the Calvin Cycle back to the light-dependent reactions?
C.
Light-Dependent Reactions (LDR)
What do light-dependant reactions use energy from light to produce?
Now state the ‘key concept’ about LDR here.
1. Look at Figure 8-10 in the book, and answer the following questions. Where are
these LDR occurring?
2. Where is water broken down?
3. Where are two places that chlorophyll absorbs the energy of sunlight?
4. Where and how is ATP produced in this process?
5. How is NADPH produced in this process?
6. Define ATP synthase:
D.
The Calvin Cycle
What happens during the Calvin Cycle?
Now state the ‘key concept’ about the Calvin Cycle here.
1. Look at Figure 8-11. Where does the Calvin Cycle take place?
2. What enters the Calvin Cycle from the atmosphere?
3. Where do the ATP and the NADPH come from ?
4. What is the product of this cycle?
5. What happens next to the 3-carbon molecules?
6. How is the cycle completed?
E.
Factors Affecting Photosynthesis
List 3 important factors that affect photosynthesis. Give examples of the impact of
elevated and decreased levels of them.
