During non-cyclic photophosphorylation in which of the following , `4e^(-)` produced through photolysis will enter

Options

A. PS-II
B. PC
C. PQ
D. PS-I

Answer

A

Explanation

Non cyclic photophosphorylation involves both PS-I and PS-II. The process begins with the absorption of ilght energy by PS_II. As light energy is absorbed , `4e^(-)` become excited from chlorophyll `-a` at the reaction centre. The `4e^(-)` released by these molecules are accepted by an electron-acceptor-substance. the other effect of this event is that photolysis of water is induced. the chlorophyll-a molecules n PS-II act as strong oxidising agent As described earlier, 4 molecules of `H_(2)O` are thus decomposed through light-induced energy. the `4H^(+)` ions become associated with 2 NADP. The `4OH^(-)` ions are associated with the release of oxygen. the four electrons `(4e^(-))` released from 4 `OH^(-)` are received by chlorophyll-a molecules at reaction-centre of PS-II
