The objectives of this problem set are to test your understanding of how light energy is converted into different forms of chemical energy during photosynthesis, to review the equations for the light reactions of photosynthesis, to study the pathway for electron transport during cyclic and non-cyclic photophosphorylation, and to explore the mechanism for coupling electron transport to ATP synthesis.

Instructions: The following problems have multiple choice answers. Correct answers are reinforced with a brief explanation. Incorrect answers are linked to tutorials to help solve the problem.

1. Chloroplast compartments
2. Energy source for ATP formation
3. Overall redox reaction
4. Result of electron transport
5. Overall energy source
6. Events during light reaction
7. Cyclic photophosphorylation
8. Equation for light reaction
9. Fate of excited pigment molecules
10. Overall result of photosynthesis
11. Photosystem II features
