Electron transport inhibitors:
Various inhibitors of specific electron carriers are known and were used in the real studies to determine the order of the parts in the respiratory chain for examples:
-amytal inhibit and rotenone transport electron at NADH-Q reductase and so prevent NADH oxidation but the oxidation of FADH2 can still occur since this feeds electrons into the chain at CoQ instance example past the point of inhibition;
- at the Q-cytochrome c reductase complex antimycin A inhibits electron transport ;
- cyanide (CN-), azide (N3 -) and carbon monoxide (CO) all inhibit cytochrome c oxidase.
