Botany Exam 2, Properties of Light, Photolysis, Rubisco - Coggle Diagram

- - - - Carbon shuffling
    - - Rubisco breaks CO2(from stoma) into PGA
  - - - noncyclic
        
        start w/ H2O
        
        NADPH is final e- acceptor
        
        more powerful energy carrier than ATP
      - Cyclic
  - - - Reaction Center P680
        
        primarily Chlorophyll B
      - oxygen evolving complex
        
        H20->O2+H+(protons)+ electrons
        
        O2 leaves through stoma
    - - Reaction Center P700
        
        Primarily Chlorophyll A
        
        Together power ATP synthase through etc
  - - - Most Plentiful
        
        Peak absorbance more extreme than type B
        
        porphyrin ring w/ hydrocarbon tail (good structure for chillin in a membrane)
    - - Second most common
    - - Carotenoids
        
        Vitamin Beta Carotene
        
        Visible in Fall
        
        Act as a sunscreen
  - - - reaction center- specialized chlorophyll a
  - - - layers of photosynthetic bacteria/cyanobacteria
        
        oldest known fossilized organism
      - 3.5 bya
    - - aprox 2 bya
        
        rusty belts in rock show us when Oxygen was plentiful
