Photosynthesis - Coggle Diagram

- - - - The initial step in photosynthesis
        
        Excited electrons travel from PSII to PSI
        
        Oxidizes water, generating O2 and H+
        
        Releases energy in electron transport chain (ETC)
        
        Energy used to make H+ electrochemical gradient
    - - Primary role to make NADPH
        
        Addition of H+ to NADP+ contributes to H+ gradient by depleting H+ from the stroma
    - - Achieved by photophosphorylation
      - Driven by flow of H+ from thylakoid lumen into
        stroma via ATP synthase
    - - NADPH
      - ATP
      - O2
    - - Noncyclic
        
        begin at PSII and transfer to NADPH
        
        Produces ATP and NADPH
      - cyclic
        
        releases energy to transport H+
        into lumen driving ATP synthesis
        
        Produces only ATP
- - - - Membrane forms thylakoids
      - Enclose thylakoid lumen
  - - - Take place in thylakoid membranes
      - Produce ATP, NADPH and O2
      - Use light energy
    - - Occurs in stroma
      - Uses ATP and NADPH to incorporate CO2 into
        carbohydrate
- - - - C3 plants make 3PG
    - - Adds O2 to RuBP eventually releasing CO2
    - - -hot and dry environments
        -when CO2 low and O2 high
