etc in mitochondria

It is for the ETC in mitochondria... there r 5 complexes in inner mitochondrial membrane... the electron flow is like this.. FMN ----> FeS ------> Co Q(coenzyme Q or ubiqionone) --- reduced CoQ ---> cyt b--->FeS ----> cyt c-----> cyt a---> cyt a3 ----> to oxygen ion. or if FADH2 is present, then FAD ----> FeS ---> coQ then the pathway is similar... so for this, i came up with a mnemonic... Fins of Foetus of Corkfish and Belly of Cat arent Analogous stri (girl in sanskrit) every ' of' stands for FeS ... Corkfish = CoQ arent = cyt a analogous stri = cyt a3 belly = cyt b FINS = FMN Foetus = FAD plz develop it if possible.. but it is more than enough for biology students to memorise this cycle/...
