  1. Chapter 10Photosynthesis

  2. Chapter 10Photosynthesis How do the reactant molecules of photosynthesis reach the chloroplasts in leaves?

  3. Chapter 10Photosynthesis CO2 H2O

  4. Chapter 10Photosynthesis CO2 H2O

  5. Chapter 10Photosynthesis How did the use of an oxygen isotope help elucidate the chemistry of photosynthesis?

  6. Chapter 10Photosynthesis How did the use of an oxygen isotope help elucidate the chemistry of photosynthesis? 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O

  7. Chapter 10Photosynthesis Describe how the two stages of photosynthesis are dependent on each other.

  8. Chapter 10Photosynthesis ATP NADPH LIGHT DARK

  9. Chapter 10Photosynthesis ATP NADPH LIGHT DARK NADP+ ADP

  10. Chapter 10Photosynthesis What color of light is least effective in driving photosynthesis? Explain.

  11. Chapter 10Photosynthesis What color of light is least effective in driving photosynthesis? Explain.

  12. Chapter 10Photosynthesis Compared to a solution of isolated chlorophyll, why do intact chloroplasts release less heat and fluorescence when illuminated?

  13. Chapter 10Photosynthesis

  14. Chapter 10Photosynthesis

  15. Chapter 10Photosynthesis

  16. Chapter 10Photosynthesis glucose

  17. Chapter 10Photosynthesis

  18. Chapter 10Photosynthesis

  19. Chapter 10Photosynthesis

  20. Chapter 10Photosynthesis

  21. Chapter 10Photosynthesis

  22. Chapter 10Photosynthesis In the light reactions, what is the electron donor? Where do the electrons end up?

  23. Chapter 10Photosynthesis In the light reactions, what is the electron donor? Where do the electrons end up? H2O NADPH

  24. Chapter 10Photosynthesis To synthesize one glucose molecule, the Calvin cycle uses _____ molecules of CO2, _____ molecules of ATP, and _____ of NADPH.

  25. Chapter 10Photosynthesis To synthesize one glucose molecule, the Calvin cycle uses _____ molecules of CO2, _____ molecules of ATP, and _____ of NADPH. 6 18 12

  26. Chapter 10Photosynthesis Explain why the high number of ATP and NADPH molecules used during the Calvin cycle is consistent with the high value of glucose as an energy source.

  27. Chapter 10Photosynthesis Duh!

  28. Chapter 10Photosynthesis Explain why a poison that inhibits an enzyme of the Calvin cycle will also inhibit the light reactions.

  29. Chapter 10Photosynthesis ATP NADPH LIGHT DARK NADP+ ADP

  30. Chapter 10Photosynthesis Explain why photo respiration lowers photosynthetic output for plants.

  31. Chapter 10Photosynthesis Oxygen replaces CO2. No carbon is fixed. ATP is used.

  32. Chapter 10Photosynthesis How would you expect the relative abundance of C3 versus C4 and CAM species to change in a geographic region whose climate becomes much hotter and drier?

  33. Chapter 10Photosynthesis C3 C4 CAM

  34. Chapter 10Photosynthesis C3 C4 CAM
