Photosynthesis - Coggle Diagram

- - - - Antenna complexes
        
        Can be hit by photon in reaction center (or vibrate to chlorophyll A)
        
        Electrons in the porphyrin head get excited
        
        Goes down in energy as it progresses through photosystems
        
        Vibration is called "resonance energy"
      - Light harvesting complexes
    - - Chlorophyll
        
        Absorbs red and blue light but reflects green light (which is why most plants are green)
      - Molecule that captures light photons
    - - A photon hits the chlorophyll and an electron is excited (photoexcitation)
        
        The photon leaves the chlorophyll via a mobile electron carrier
        
        Missing it's electron, the chlorophyll grabs a water and splits it (oxidizes water) for a new electron, producing H+ and diatomic oxygen as byproducts
        
        Meanwhile, the photon/electron goes to the cytochrome complex, which uses its energy to pump another H+ into the thylakoid and transfers the photon to PSI
        
        All the H+ in the thylakoid helps ATP synthase make ATP
        
        From PSI, the photon goes to NADP+ reductase to make NADPH
        
        NADP+ is the final electron acceptor
        
        This process is called photophosphorylation
        
        Pumps are driven by photons entering lower energy states
    - - Thylakoids contain pigments, and a stack of thylakoids are granum
        
        Inside the thylakoids are the lumen, and the stroma surrounds the thylakoids
        
        Thylakoid membranes are phospholipid bilayers
    - - Photosystem II (P680) was discovered after Photosystem I (P700)
      - Photosystem II proteins
        
        Chlorophyll A
        
        Pheophytin
        
        H2O
        
        Plastoquinoun
        
        cytochrome B6F complex
        
        Plastocynine
      - Photosystem I proteins
        
        Chlorophyll
        
        Ferodoxin
        
        NADPH
  - - - Where it occurs
      - Compare to ATP synthesis in mitochondria
    - - Role of Rubisco enzyme
      - CO2 enters through pores on the bottom of leaves (stomata)
      - Four Phases
        
        Reduction and carbohydrate formation
        
        Regeneration
        
        Carbon fixation
      - Occurs in the stroma
      - Uses ATP, CO2, and NADPH to produce G3P (phosphoglyceraldehye)
