Unit Objectives: Photosynthesis
At the conclusion of this unit, you should be able to:
1. Distinguish between autotrophic and heterotrophic nutrition and give examples of
organisms that use each.
2. Distinguish between photosynthetic and chemosynthetic autotrophs by comparing the
sources of free energy for each and giving examples of organisms from each group.
3. Identify the type of organism that first carried out photosynthesis; its role in oxygenating
the atmosphere and link to photosynthesis in eukaryotic organisms.
4. Describe the location of a chloroplast within a plant AND the structure of an individual
chloroplast (include: grana, stroma, thylakoid, photosystem, mesophyll cell and leaf in
your description).
5. Write the summary equation for photosynthesis and explain the role of REDOX reactions
in photosynthesis.
6. Describe the role of chlorophyll and other pigments in the transfer of energy during
photosynthesis.
7. List the components of a photosystem and identify their location within the chloroplast.
8. Explain how the structure of a chloroplast is essential to its function in photosynthesis.
Be as specific as possible.
9. Summarize the light reactions of photosynthesis with an equation and their cellular
location.
10. Trace energy flow through the process of photosynthesis including PI, PII, NADP, and
ADP.
11. Describe the process of photophosphorylation in chloroplasts (including formation of the
proton gradient and chemiosmosis) AND identify similarities and differences between
photophosphorylation in chloroplasts and oxidative phosphorylation in mitochondria.
12. Briefly summarize the carbon-fixing reactions of the Calvin-Benson cycle by identifying
reactants, product and location of the events of this cycle.
13. Describe the role of ATP and NADPH in the Calvin-Benson Cycle.
14. Describe how the rate of photosynthesis is impacted by environmental conditions.
15. Describe the fate of photosynthetic products (including sugars, oxygen and water).
