Detailed explanation-1: -Answer. NADPH is formed when ferredoxin transfers electrons to an electron carrier.
Detailed explanation-2: -During photosynthesis, electrons are removed from water and transferred to the single electron carrier ferredoxin. Ferredoxin: NADP+ reductase then transfers an electron from each of two ferredoxin molecules to a single molecule of the two electron carrier NADPH.
Detailed explanation-3: -Ferredoxin transfers electrons to NADP+, forming NADPH.
Detailed explanation-4: -Function. Ferredoxin (Fd) is found in chloroplasts which mediates electron transfer and contains an iron-sulfur cluster. It is involved in the photosynthesis process where its iron atoms accept or discharge electrons when they are being oxidized or reduced.
