  1. Let’s talk food! OM NOM NOMNOMNOM

  2. Molecules store chemical energy in their bonds

  3. How much energy do we get?

  4. 36 ATP ~36 ATP ~146 ATP

  5. Plants eat like animals?

  6. Surviving without the sun!! chemosynthesis Deep Sea Vents

  7. C6H12O6+ 6 O2 6CO2 + 6 H2O

  8. Light transmit energy as wavelengths

  9. What wavelengths drive photosynthesis?

  10. Name that organelle!

  11. Photosynthesis takes place in two parts.

  12. Light Dependent Reaction • chlorophyll absorbs energy from sunlight • energized e- enter the electron transport chain • H2O is split; O2 is waste • H+ are transported across the thylakoid membrane

  13. Light Dependent Reaction • chlorophyll absorbs energy from sunlight • energized e- used to make NADPH • NADPH is transferred to light-independent reactions

  14. So where does ATP come from?

  15. Recap of Light Dependent Reaction Light excites chlorophyll ATP is made by chemiosmosis NADPH is made H2O is split & e- are replaced in chlorophyll O2 is made

  16. Now, the second half… Light Independent Reaction aka Calvin Cycle

  17. The Overview • CO2 enters • ATP is the energy used to “start” the reaction • H+ & e- are used from NADPH • Glucose is made • “Rinse and repeat” • Molecules are recycled

  18. Photosynthesis
