TCA cycle by mnemonics.... its fun...

i'll present another mnemonic.. very fine one that i came up with... ( that should be decided by you)...

Citric acid cycle ....

citric acid ---> cis-aconitic acid----> isocitric acid--(NAD ---> NADH2) --> oxalosuccinic acid (OSA) --> alpha-ketoglutaric acid (@-KGA)

--(NAD --->NADH2)-> succinyl coA ,---> succinic acid ------> fumaric acid ------> malic acid --(NAD--->NADH2)--> oxalo acetic acid (OAA)----> again citric acid....

and to complicate things ( not actually !!!) in some steps NADH2 is formed, and in some FADH2 is formed.....

so.. here is my mnemonic...

Commonly, All sisters Isolate OSAma's KG- amputates Sharply Suceeding in Filming Meteorates (actually meteorites) Ascending only above...

now..plzz note that whenver a word ends with -ate here, in that step, NADH2 is formed.....that

here... Commonly - citric acid

All sisters = aconitic acid cis form

Isolate - isocitric acid....

OSAma = oxalosuccinic acid

KG-amputate = @-KGA

Sharply= succinyl coA

suceeding = succinic acid

filming = fumaric acid...

metoerate = malic acid

only ascending above = OAA

hope it helps...

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/...

Mnemonic: etc photosynthesis.... the best mnemonic i ever created..

the electron transport chain during photosynthesis...

there is one Z- scheme and one cyclic pathway... cyclic pathway is the main one and is most important as Z-scheme is just an extension of cyclic pathway...

so here it is..

plastoquinone(PQ) ----> reduced plastoquinone(PQH2)-----> FeS ---> cytochrome f (cyt-f) ---> plastocyanin (PC) -----> P-700---> FeS --> Ferradoxin (FD)------> cytochrome b (cyt b) ---> again PQ...

now... this can be memorised as ... Parrot Pocketed fully filled plastic cans 700 to Fill its Food breaking site

breaking site = cyt b

food = Ferradoxin

Plastic can = plastocyanin
