Non Cyclic Phosphorylation
Electron Transport system
This is a process whereby the green parts of a plant can use the energy of the
sun along with a green pigment, chlorophyll, Carbon Dioxide and Water, to make
their own simple sugar. This sugar is then used primarily as a fuel in the
process of Respiration.
Where does it occur?
As stated before, the process of Photosynthesis occurs in the green parts of
all plants. This is due to the presence of special organelles called
Chloroplasts, which contain a green pigment called Chlorophyll.
- The Light Dependant Phase is made up of the following two processes:
- Cyclic Photophosphorylation
in which ATP is formed to fuel to Light Independent Phase (Dark Phase)
Photophosphorylation in which water is split to form H2
and O2. The O2 is released through the stomata and the H2 is taken into the
Light Independent phase in order to reduce Phosphoglyceric acid to
- The Light Independent Phase in which Glucose is made.
