Cellular Energetics - Coggle Diagram

- - - - inputs: light energy and water,
        outputs: oxygen, ATP, NADH
      - PSII absorbs light energy. Light energy excites electrons in chlorophyll. The energy electrons leave chlorophyll and travel down the ETC
      - To replace the electrons lost from PSII, water molecules split, in phtotlysis. Oxygen released as byproduct
      - Excited electrons from PSII pass through the ETC. As electrons move, they release energy, which is used to pump H+ ions into the thylakoid lumen. Creating proton gradient(high concentration of H+ inside
      - In chemiomosis, the H+ gradient drives the synthesis of ATP. ATP synthase uses the flow of H+ ions from high to low concentration to convert ADP+Pi into ATP
      - The electrons from PSII eventually reach PSI. Light energy re-excites the electrons in PSI, boosting them to higher energy level. These high energy electrons passed through the electron carrier NADP+, reducing it to form NADPH
