Energy: ATP

Photosynthesis
1. Autotrophic organisms make organic compounds from Carbon Dioxide. They rely on Photosynthesis.
2. Light Dependent Reaction
  1. Electron Transport Chain
    1. Makes ATP.
    2. Aims: 1) Produce ATP. 2) Photolysis of Water
    3. 1. A photon of light hits a chlorophyll molecule. Energy is transferred to the electrons.
      1. 2. Electrons excited: Raised to higher energy level
        3.Leaves Chlorophyll molecule immediately
        4. Picked up by an electron carrier/acceptor. Through a series of redox reactions and moving down acceptors at different energy levels, energy is then released to help form ADP+Pi--->ATP
        5.NADP then picks up the electron, becoming reduced NADP
        Reduced NADP
        6. The Chlorophyll now needs to be restocked of electrons, so photolysis of water occurs.
        Photolysis
        4OH- - 4e- (lost to chlorophyll) ---> O2 + 2H2O
        Oxygen
        ATP
  2. Occurs in Thylakoid
3. Light Independent Reaction
  1. Calvin Cycle
  2. Occurs in the Stroma
4. 6CO2+6H20---->C6H12O2+6O2
Needed for life
1. Consisting of an Adenine base, ribose sugar and triphosphate. Each bond between the phosphates is broken to release energy through a hydrolysis reaction. This is catalysed by ATPase. ADP is then formed and a free inorganic phosphate. It is a reversible reaction.
  1. Redox
