WebReduced ferredoxin, unable to reduce NADP+ returns the electron to PS I via cytochrome b 6, plastoquinone (PQ), cytochrome-f and plastocyanin. 3. The electron transport is called cyclic because the electron emitted from PS I returns back to PS I passing through several intermediate carriers. Hence, the correct answer is 'Cyt.b6'.
