Energy: ATP
- Photosynthesis
- Autotrophic organisms make organic
compounds from Carbon Dioxide.
They rely on Photosynthesis.
- Light Dependent Reaction
- Electron
Transport Chain
- Makes ATP.
- Aims: 1) Produce ATP.
2) Photolysis of Water
- 1. A photon of light
hits a chlorophyll
molecule. Energy is
transferred to the
electrons.
- 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.

- Needed for life
- 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.
