  1. Photosynthesis Chapter 8

  2. Fig. 10-4 Photosynthesis • http://bcs.whfreeman.com/thelifewire/content/chp08/0802001.html

  3. Energy in Living Systems • Autotrophs – • Heterotrophs -

  4. Chemical Energy • Energy from the sun must be converted to chemical energy for cells. • ATP • ADP

  5. ATP and ADP

  6. Uses of ATP

  7. Uses of ATP

  8. Comparing ATP to Glucose • Why do cells not store all of their energy in ATP compounds? • Coins vs. Bills • Glucose stores 90 times the energy of ATP.

  9. What must be taken into the leaf for photosynthesis to occur?

  10. light Calvin light Calvin

  11. These leaf openings are stomata. What is the function of stomata?

  12. An Overview of Photosynthesis • What are the products of the Calvin Cycle?

  14. Products of the ETC • The electron transport chain produces: • Oxygen from the breakdown of water • NADPH from NADP+ and H+ (+energy from electrons) • ATP from ADP in the ATP synthase protein as H+ pass from one side of the thylakoid membrane to the other • The NADPH and ATP are used in the Calvin Cycle

  15. Calvin Cycle

  16. Products of the Calvin Cycle • 6 Carbon Dioxide molecules from the atmosphere are used to make 1 6-carbon sugar molecule. • The energy from ATP is used and leaves ADP • The high-energy electrons from NADPH are used and leaves NADP+ • ATP and NADP+ are recycled in the ETC
