Question : Cyclic-photophosphorylation results in the formation of

Answer»

NADPH
ATP and NADPH
ATP,NADPH and `O_(2)`
ATP

Solution :Cyclic-photophosphorylation involves only pigment system-I and result in the formation of ATP only. When the photons activate PS-I, a PAIR of electrons are raised to a higher energy level. They are captured by primary acceptor which passes them on to ferredoxin, PLASTOQUINONE, cytochrome complex, plastocynin and finally back to reaction centre of PS-I, i.e., `P_(700)` At each step of electron transfer, the electrons lose potential energy. their trip down hill is caused by the transport chain to pump `H^(+)` across the thylokoid membrane. The proton gradient thus established is RESPONSIBLE for forming ATP (2 molecules). No reduction of NADP to NADPH+`H^(+)`
