      6CO2 + 6H2O--------------> C6H12O6 + 6O2

photosynthesis

 

To explain the process of light dependent reaction, we should know about the photosystem.

                           photosystem I (PS I) and

                           photosystem II (PS II).

                               P700 in PS I
                               P680 in PS II
                    (P stands for pigments)
