Photosynthesis can be split into 2 stages:
The Light-Dependent Reaction and the Light-Independent Reaction.
I'll go through the Light-Dependent Reaction for you :D
- The Light-Dependent Reaction needs light energy, as the name suggests.
- Takes place in the thykaloid membranes of the chloroplasts.
- The light is absorbed by pigments in the photosystems and converted to chemical energy.
- The light energy is used to add a phosphate group to ADP to form ATP, and to reduce NADP. ATP transfers energy and reduced NADP transfers hydrogen to the Light-Independent Reaction.
- During the process H2O is oxidised to O2 and the oxygen is given off as waste (which is extremelyyy good for us!)
In the Light-Dependent Reaction, ATP is made by photophosphorylation. This means the light energy is used for the following things:
1) Making ATP…
