Chapter 7: Photosynthesis

Learning Outcomes

After studying this chapter, you should be able to accomplish the following outcomes.

Photosynthetic Organisms

1. List the types of organisms that carry on photosynthesis.
2. Identify the main pars of a chloroplast.
3. Show that photosynthesis is a redox reaction that produces a carbohydrate and releases O₂.

4. Divide photosynthesis into two sets of reactions, and associate each set with either capture of solar energy or reduction of carbon dioxide.

5. Explain why leaves are green, with reference to the electromagnetic spectrum.
6. Trace the path of an excited electron from its absorption of solar energy to the production of ATP and NADPH.
7. Describe how the thylakoid membrane is organized to produce ATP.

8. Describe the three phases of the Calvin cycle, and indicate when ATP and/or NADPH are involved.
9. Draw a diagram showing that G3P is a pivotal molecule in a plant's metabolic pathway.

10. Compare and contrast three modes of photosynthesis and tell how each is adapted to a particular environment.
