List out the bioenergetics of light reaction.

Explanation

Bio energetics of light reaction :
To release one electron form pigment system it requires two quanta of light .
One quantum is used for transport of electron from water to PS I.
Second quantum is used for transport of electron from PSI to `NADP^(+)`.
Two electrons are requried to generate on `NADPH + H^(+)`.
During Non - Cyclic electron transport two `NADPH + H^(+)` are produced and it requires 4 electrons.
Transportaion of 4 electrons requires 8 quanta of light .
