Explanation / Answer

PART A

amytal and rotenone

Amytal and rotenone inhibit the transfer of electron in NADH dehydrogenase

Rotenone and amytal block NADH dehydrogenase (complex 1) in the respiratory chain, blocking the flow of electrons from NADH to CoQ

PART B

Antimycin A

Antimycin inhibits electron flow from cyt b to cyt c1 in complex III

cytochrome bc1 complex sometime called cytochrome c or complex III, is the third complex in the electron transport chain playing a critical role in biochemical generation of ATP.

PART C

Cyanide and carbon monoxide

Cyanide and carbon monoxide inhibit the flow of electron through cytochrome c oxidase (complex IV)

Cyanide and carbon monoxide inhibit electron transport in Complex IV. They inhibit electron transfer by binding tightly with the iron coordinated in Cyt a3
