Question : List out the bioenergetics of light reaction.

1.	Question : List out the bioenergetics of light reaction.
Answer» Solution :Bio energetics of lightreaction : To release ONE electron form pigmentsystem it requires two QUANTA of light . Onequantumis usedfor transportof electronfrom water to PS I. Secondquantum is usedfor transportof electron from PSI to `NADP^(+)`. Two electrons are requried to GENERATE on `NADPH + H^(+)`. DuringNon - Cyclic electron transporttwo `NADPH+ H^(+)` are producedand it requires 4 electrons. Transportaionof 4 electrons requires 8 quanta of light .
