Question

Primary electron acceptor in non-cyclic photophosphorylation is

looooooooooveeeeeeeeeeeeeee u alllllllll

Answer 1

Answer:

The electrons lost by P680 (PS-II) are taken up by P700 (PS-I) and do not get back to P680 i.e., unidirectional and hence it is called non- cyclic phosphorylation. The electrons pass through the primary acceptor, plastoquinone (PQ), cytochrome complex, plastocyanin (PC) and finally to P700.
