Photosynthesis - Coggle Diagram

- - - - Adenosine Diphosphate (ADP) is similar to ATP in the sense that it is also made up of adenine, ribose, and phosphate, but the key difference is the fact that ADP has one less phosphate group than ATP. This means that, while ADP can still store and release energy, it stores less energy than ATP because it has one less phosphate bond.
        
        A good way of remembering the key difference between ATP and ADP is thinking about them as batteries. ADP is more of a half full battery which is able to store and release lower amounts of energy, than ATP which is a fuller battery and is able to release higher amounts of energy.
  - - - The pigments in this photosystem take in energy from light and release high energy electrons. These high energy electrons are moved through the electron transport chain and go through the cycles explained above.
    - - Electrons in photosystem II lose their energy as they are circulated through the membrane. In photosystem I, after these electrons come into contact with light, they regain their energy. After, they continue through yet another transport chain where their sole function is to turn NADP+ into NADPH.
