Question

What 5 poisons affect each part of the ET chain?

A) Rotenone, Antimycin A, Cyanide, Carbon Monoxide, 3-Nitropropionic Acid
B) Oligomycin, Malonate, Hydrogen Peroxide, Amobarbital, Succinylacetone
C) Dinitrophenol, Atractyloside, Malonate, Cyanide, Amobarbital
D) Cyanide, Antimycin A, Oligomycin, Atractyloside, 3-Nitropropionic Acid

Answer 1

The 5 poisons that affect each part of the Electron Transport Chain (ETC) are: Rotenone, Antimycin A, Cyanide, Carbon Monoxide, and 3-Nitropropionic Acid.

Step-by-step explanation:

The 5 poisons that affect each part of the Electron Transport Chain (ETC) are:

1. Rotenone: blocks the transfer of electrons from Complex I
2. Antimycin A: inhibits the flow of electrons at the second site
3. Cyanide: inhibits cytochrome c oxidase at the third site
4. Carbon Monoxide: also inhibits cytochrome c oxidase at the third site
5. 3-Nitropropionic Acid: uncouples oxidative phosphorylation
