  1. The end products of the light dependent • reactions of photosynthesis are • ADP, H2O, NADPH • ADP, PGAL, RuBP (RuDP) • ATP, CO2, H2O • ATP, NADPH, O2 • CO2, H+, PGAL Answer: d

  2. The function of water in photosynthesis • is to • combine with CO2 • absorb light energy • supply electrons in the light-dependent • reactions • d. Transport H+ ions in the light-independent • (dark) reactions • e. Provide O2 for the light-independent • reactions Answer: c

  3. When hydrogen ions are pumped out of the • chloroplast stroma, across the thylakoid • membrane, and into the thylakoid space, the • result is • damage to the chloroplast. • the reduction of NAD • the restoration of the Na-K balance across the • membrane. • d. the creation of a proton gradient. • e. the lowering of pH in the chloroplast stroma. Answer: d

  4. Which of the following processes is carried • out more efficiently by a C4 plant than by • a C3 plant? • Light absorption • Chemiosmotic coupling • Photolysis • Fixation of CO2 • Transport of sugars Answer: d

  5. Photosynthesis Chapter 10

  6. Needed: Light Photons(discrete packets of energy) High energy photons (UV and above) cause cellular damage by denaturing organic molecules Energy Only ~ 42% of solar radiation Makes it to the surface

  7. Needed: Chlorophyll (blue green in color) (yellow green in color)

  8. Also present: Carotenoids

  9. Fall Leaves

  10. (chlorophyll In membranes)

  11. Photosystems

  12. Cyclic Photophosphorylation

  13. Noncyclic Photophosphorylation (light reaction)

  14. Thylakoid space Stroma Chemiosmosis

  15. Comparison of chemiosmosis in mitochondria and chloroplasts

  16. Comparison of chemiosmosis in mitochondria and chloroplasts Campbell; Fig. 10.15

  17. Dark reaction (Calvin-Benson cycle) (PGA) (PGAP) (PGAL) (PGAL)

  18. Hot, dry weather

  19. C4 Photosynthesis
