For photosynthesis in green plants, the electron donor for the light dependent reaction is water.
What are the events during light dependent reaction?
- During photosynthesis, the light dependent reactions occur in the thylakoids. The electrons are provided by the breakdown of water.
- Within the thylakoid membrane, chlorophyll captures energy from the sun in the form of photons and breakdown the water molecules producing energy in the form of ATP and NADPH.
- Chlorophyll pigment is present in both Photosystem I (PS I) and Photosystem II (PS II) which are also known as light harvesting complexes.
- Light reactions begin with the excitation of electron in chlorophyll of PS II by sunlight. This excited electron leaves the chlorophyll and travels via electron transport chain.
- To fill the void created by the loss of an electron, PS II drives an electron by splitting of water molecule.
