Inhibitors of electron transport chain mnemonic

Inhibitors of electron transport chain mnemonic
In this post, we learn a mnemonic that tells us all about the inhibitors of the ETS!

The mnemonic is, "CRAP Tightens Muscle AND Produces Muscle ACHe"

Complex I inhibitors mnemonic
C - Chlorpromazine
R - Rotenone
A - Amobarbital
P - Piercidin A

Complex II inhibitors mnemonic
Tightens - Thenoyltrifluoroaceteate
Muscle - Malonate

Complex III inhibitors mnemonic
A - Antimycin A
N - Naphthoquinone
D - Dimercaprol
Produces - Phenformin
Muscle - Myxothiazole

Complex IV inhibitors mnemonic
A - Azide
C - Carbon monoxide (CO), Cyanide (CN-)
H - Hydrogen sulphide (H2S)

That's all!

Thanks Fayaz, for submitting this mnemonic, however, a part of it was wrong and that's why I modified it to match the facts :)



  1. Hi. Myxothiazole seems to be a complex III inhibitor...

    1. Oh yes, I Googled it and realized it is.

      You could modify the mnemonic to:

      "CRAP tightens muscle and produces muscle ache "

      I'll change the image too when I get the time!

    2. Thanks! I almost mugged up the wrong thing! But I've changed the mnemonic. Very useful website BTW. Keep posting..

    3. Oh I'm sorry for that.. Should have cross checked facts before publishing it. Thanks for telling us and please let us know if there are any other errors!
