The Relationship between Cellular Respiration and Photosynthesis…

- - - - Photosystem II captures light energy and releases an electron.
        
        Electrons travel down the Electron Transport Chain. It produces ATP when hydrogen ions cross the gradient with ATP synthase. Oxygen is released.
        
        Photosystem I captures light energy and releases an electron
        
        Energized electrons that are from Photosystem I get captured by NADP+ and mixed with Hydrogen ions to make NADPH.
      - Light energy converts to chemical energy and produces oxygen.
    - - Carbon is absorbed which is reduced to CH2O because it uses ATP and NADPH. There are 3 steps.
  - - - Pyruvate then enters the mitochondrial matrix and is converted to 2- carbon acetyl group and forms acetyl-CoA. This is where electrons are picked up by NAD. CO2 is transported out of the mitochondria.
    - - Oxidation occurs and NAD+ is reduced to NADH. Carbon dioxide is released. The production of ATP occurs. Oxidation happens when FAD reduces down to FADH+ and NAD+. The cycle keeps repeating.
    - - Glucose is broken down into 2 pyruvates.
    - - NADH and FADH+ electrons are passed until they get oxygen. When oxygen combines with hydrogen ions you get water. The hydrogen ions get pumped into the intermembrane. This produces a gradient. The ATP synthase synthesizes to ATP from ADP. ATP is energy which can be used for cellular work.
- - - - Chloroplasts contain thylakoids. Thylakoids contain chlorophyll which helps absorb the solar energy that helps photosynthesis happen.
      - The stroma is in the chloroplasts. This is where carbon dioxide is reduced into a carbohydrate.
  - - - Preparatory reaction takes place in the mitochondria.
      - Citric Acid Cycle takes place in the mitochondrial matrix.
      - Glycolysis takes place in the cytoplasm.
      - Electron Transport Chain takes place in the mitochondrial membrane.
