In cyclic photophosphorylation, the electron released by reaction centre `(P_(700))` is ultimately accepted by

Options

A. ferrdoxin
B. `NADP^(+)`
C. reaction centre `(P_(700))`
D. plastocyanin.

Answer

C

Explanation

In cyclic photophosphorylation, and electron expelled by the excited photocentre `(P_(700))` is returned to its after passing through a series of electron carrieres its pjotocentre `P_(700)` extrudes and electron with a gain of 23 kcal/mole of energy after absorbing a photon of light (hv) After losing the electron passes through a series of carriers including X or `A_(0)` (a special `P_(700)` chlorophyll molecule). `A_(1)` (a quinone). FeS complexes `(FeS_(x)FeS_(A),FeS_(B))`, ferredoxin (Fd), plastoquionone (PQ), cytochrome b-1 complex and platocyanin (PC) before returning to photocentre.
