What are photoautotrophs? What do photoautotrophs do during photosynthesis with respect to energy? What are the two stages of photosynthesis? How are the two stages of photosynthesis connected to each other? Overall in photosynthesis, what is(are) the initial source of energy, initial source of electrons and electron carriers? 6. In eukaryotes, where does photosynthesis take place and specifically each of the two stages? 7. Describe the stroma versus the thylakoids in chloroplasts. 8. What is the function of pigments? 9. Describe the three potential fates of excited electrons in pigments? Which is essential for photosynthesis? 10. What is a primary electron acceptor? 11. Which chlorophyll is the most important in photosynthesis and why? 12. Explain how the experiment that supports the hypothesis that chlorophyll strongly absorbs light in the red and blue range. 13. Describe the structure of a photosystem. 14. What is the difference between P680 and P700? 15. Explain linear electron transport in photosynthesis and what is the end result? 16. How is it possible to make ATP during the light-dependent stage of photosynthesis? 17. How many photons are required to move an electron down the electron transport? 18. What is the difference between the linear electron transport versus the cyclic electron transport? 19. During the Calvin cycle, what is reduced? What donates electrons? What provides energy? 20. What is rubisco? 21. Describe the three main stages of the Calvin cycle? How many ATP, NADPH, products, reactants? 22. Describe how rubisco can act both as a carboxylase and an oxygenase? 23. What is photorespiration? 24. What is a stomata? How does it work? 25. What is the reason why some plants use a C4 photosynthesis? 26. During C4 respiration, what are the intermediate carbon molecules? 27. What is the enzyme used in C4 respiration that fixes CO2 and how is it different from rubisco? 28. Why is the Calvin cycle also called the C3 cycle? 29. What happens to malate during C4 respiration and when does this happen? 30. In C4 plants, carbon dioxide is captured in which type of cells? 31. In C4 plants, where does most of the Calvin cycle take place? 32. How do CAM plants regulate their photosynthesis with respect to time of day?...
