- - - - goes through pigments until it hits reaction center
        
        captured by electron acceptor
        
        enzyme split water
        
        electron provide atp synthesis energy
        
        goes down electron transport chain
  - - - produce atp but no nadph
  - - - protein complex with two special chlorophyll molecules and primary electron acceptor
    - - consist of pigment and protein
        
        allows harvest light than one pigment
        
        act as antenna for reaction center, funnels to center
- - - - carbon fixation
        
        incorporation of carbon
        
        carbon reduced to carbohydrate by adding electron
        
        powered by NADPH using energized electrons
        
        powered by ATP
      - relies on light reaction
    - - convert solar to chemical energy
        
        chemical energy is used to form NADPH and ATP
      - light absorbed
        
        drives transfer or electron and hydrogen from water to NADP+
        
        stores energized electrons
      - generate ATP
      - photophosphorylation
        
        process of adding phosphate group to adp
        
        powered by chemiosis
  - - - oxygen from plants through stomata is from water not carbon dioxide
        
        chloroplast split water -> hydrogen and oxygen
        
        use of oxygen isotope
        
        oxygen labeled with isotope only if from water
  - - - electron transfer from water to to carbon dioxide
        
        requires energy because of electron movement
        
        energy from light
- - - - eat autotrophs
- - - - wavelength: distance between electromagnetic wave crest
        
        range from less than nanometer to more than kilometer
      - range of radiation
        
        electromagnetic spectrum
        
        radiation = visible light
        
        light made of photons
    - - measured by spectrophotometer
        
        direct light wavelength through pigment
        
        measure fraction light transmission
