Calvin Cycle by June B. Steinberg
Chapter 10 Learning Objectives:
After studying this material you should be able to:
1. Distinguish between heterotrophs and autotrophs.
2. Compare and contrast chemoautotrophs and photoautotrophs and give examples of each.
3. Describe the structure and function of chloroplasts.
4. Explain the significance of the locations of the thylakoid membrane and stroma.
5. Write the summary equation for the entire process of photosynthesis.
6. Describe how the 1st Law of Thermodynamics applies to photosynthesis.
7. Explain the role of redox reactions in photosynthesis – identify what gets oxidized and what gets reduced.
8. Summarize what happens in the two main events of photosynthesis.
9. Define and distinguish between action and absorption spectra for chlorophyll.
10. Trace the route electrons flow through Photosystems II and I.
11. Write a summary equation for the light reactions only.
12. Compare and contrast chlorophyll a, chlorophyll b, and carotenoids.
13. Compare and contrast chemiosmosis and the processes of oxidative phosphorylation and photophosphorylation in mitochondria and chloroplasts, respectively.
14. Summarize the carbon-fixing reactions of the Calvin cycle and describe changes that occur in the carbon structure of the intermediates.
15. Describe the role of ATP and NADPH in the Calvin Cycle.
16. Write a summary equation for the Calvin Cycle only.
17. Describe alternative methods of the Calvin Cycle based on environment.
18. Draw a sketch of a chloroplast, identify the structural components, and indicate where the photosynthetic energy transformations of the light reactions and the Calvin cycle take place.
19. List the inputs (raw materials) and outputs (products) of the light dependent reactions and the Calvin Cycle.
20. Describe how the light reactions and Calvin Cycle are chemically and energetically linked.
21. Describe the role of enzymes in the process of photosynthesis.
22. Explain how the following factors affect photosynthesis: stomatal opening, temperature, light intensity, water availability, and CO2 availability.
23. Explain what the plant does with the carbohydrate that is produced by photosynthesis.
