Reduction of NADP takes place in
Options
(a) cyclic photophosphorylation
(b) non-cyclic photophosphorylation
(c) oxidative photophosphorylation
(d) non-oxidative photophosphorylation
Correct Answer:
non-cyclic photophosphorylation
Explanation:
Phosphorylation takes place in two ways-cyclic and noncyclic. In noncyclic photophosphorylation high energy electrons released from P-680 (PSI) do not return to P-680 but pass through-pheophytin, plastoquinone, cytochrome b₆-f complex, plastocyan in and then enter P₇₀₀ and the excited electrons are used in the reducton of NADP to NADPH₂. When the electron from P₇₀₀ is carried by FeS (iron suphur protein complex), Fd (ferredoxin), is reduced and with the help of Fd-NADP reductase, NADP is reduced to NADP.
