photophosphorylation

Let us study about photophosphorylation,
Photophosphorylation is the process of creating ATP using a Proton gradient created by the Energy gathered from sunlight. The process of creating the Proton gradient resembles that of the electron transport chain of Respiration. But since formation of this proton gradient is light-dependent, the process is called Photophosphorylation.

1. Non-cyclic Photophosphorylation - During the movement of electrons shown in red, H+ moves across the membrane. The movement of electrons "drives" the reactions shown in blue.

2. Cyclic Photophosphorylation - During the movement of electrons shown in red, H+ moves across the membrane. These electrons don't generate NADPH, but the H+ transport can produce ATP.
I hope the above explanation was useful, now let us study about cell membrane.
