To which substance does ferredoxin transfer an electron?

In non-cyclic photophosphorylation, ferredoxin is the last electron acceptor thus reducing the enzyme NADP+ reductase. It accepts electrons produced from sunlight-excited chlorophyll and transfers them to the enzyme ferredoxin: NAD+ oxidoreductas EC 1.18.1.2.... Show More
Ferredoxin transfer an electron to NADP+Explanation:Two photosystems, photosystem I and photosystem II, are protein complexes which absorb radiant energy. This energy is used to create an electron transport chain.After the absorption of light in photosystem II, the electrons travel and transfer to photosystem I. After a second excitement through light absorption, electrons are passed to ferredoxin, and in non-cyclic transport to NADPH reductase, which ultimately transfers electrons to the final electron acceptor, NADP+...

The right answer is NADP+.Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH ....
