  1. ATP
  2. *High energy molecule
    • *“Energy currency” of the cell
    • *“Spent” to fuel many cellular processes
  3. Autotroph
    *“Self-feeders”

    *Produce organic molecules from CO2

    *Ultimate source of organic compounds

    *“Producers”
  4. Calvin cycle
  5. *CO2 is reduced to form sugars
    • **ATP and NADPH used to drive this process
    • **Dependent upon the products of the light reactions

  6. CHEMIOSMOSIS
    The light reactions capture energy through electron transport chains

  7. Chemoheterotrophs
    • organism that obtains its nourishment from organic, as opposed to inorganic, substances and does not require light energy for its metabolism.
    • (All animals, fungi, and many bacteria are chemoheterotrophic.)
  8. Chlorophyll
    A pigment that is embedded in the thylakoid membranes of chloroplasts of all eukaryotes
  9. Chloroplast
    sites of photosynthesis in eukaryotes
  10. Cyclic electron flow
    A route of electron flow during light reactions of photosynthesis involving photosystem I =producing ATP but not NADPH or oxygen
