  8. DIAGRAMS • PHOTOSYSTEM • A. photon of light • B. reaction center • C. pigment molecules of antenna

  9. A. PS II B. ETC C. PS I D. thylakoid interior E. ATP synthase F. stroma Thylakoid Disk DIAGRAM 680 700 F

  10. What wavelength is chlorophyll a at its highest peak? 425 nm What color is carotene pigment? Orange Absorption of Chlorophyll Graph DIAGRAM

  11. #1 EQUATION • For photosynthesis • 6 H2O + 6 CO2 -----> C6H12O6+ 6 O2 light

  12. What goes into the stoma? What goes out of the stoma? H20 and CO2 Water and O2 #2 Going in and out

  13. DO YOU KNOW…Plants • Are known as: (how many are true?) • consumers • Autotrophs • Producers • Herbivores • Heterotrophs • ANSWER: autotrophs and producers

  14. #3 Main function of chlorophyll • A. Make rubisco • B. Turn the leaf yellow • C. Capture sunlight energy • D. Make sugar from carbon dioxide • ANSWER: C. capture sunlight energy

  15. Do You Know????? • What is under the XXXX’s? • ANSWER: Stromal lamella XXXX

  16. #4 Chlorophyll • Absorbs what pigments the most? • ANSWER: Blue-violet and red • Reflects what pigments the most? • ANSWER: Green and yellow

  17. #5. Where does the oxygen come from? • Splitting of oxygen • Splitting of water • Pure oxygen taken into a leaf • Glucose breaking apart • ANSWER: splitting of water

  18. #6 CO2 C6H12O6 • Oxidized? • Reduced? • ANSWER: Reduced • (GER gained Hydrogens/e-)

  19. #7 Which stage actually makes the sugar (glucose)? • LIR • LDR • Krebs cycle • Calvin cycle • ANSWER: Calvin cycle (LIR)

  20. LIR LDR Calvin cycle ETC Chemiosmosis Splitting of water Stroma Thylakoid disks Stroma Thylakoid membrane Thylakoid interior (H+) through thylakoid membrane (ATP synthase) to stroma (ATP) Thylakoid interior #8 Where does it take place?

  21. Which pigments are the heaviest? Bottom (Chl b) Which pigments are the least dense? Top (xanthophyll) See Reference sheet:Paper Chromatography

  22. #9 What are the high energy molecules made in • LDR to run the LIR? • ATP and NADPH

  23. #10 What is the other name of LIR? • Krebs cycle • LDR • Calvin cycle • ETC • Chemiosmosis • ANSWER: Calvin cycle

  24. #11 What happens when a pigment molecule absorbs a photon? • Electrons leave the pigment molecules • Electrons are added to the pigment • Electrons in the pigment gain energy and are raised to an excited state • The electrons in the pigment lost energy and fall to the ground state • ANSWER: Electrons in the pigment gain energy and are raised to an excited state

  25. Of LDR? Of LIR? ATP and NADPH and oxygen Glucose and ADP and NADP #12 WHAT ARE THE PRODUCTS?

  26. #13 How many turns? • Of the Calvin cycle to produce one molecule of glucose? • 1 • 2 • 3 • 6 • ANSWER: 6
