Input (English): Question: Mitochondrial electronic transport and oxidative phosphorylation: 
 Options:  <0> They are two different processes, but coupled. Without electronic transport there will never be oxidative phosphorylation. <1> Without oxidative phosphorylation there can never be electronic transport. <2> The net yield of oxidative phosphorylation is about 2.5 moles of ATP per mole of FADH2. <3> Cyanide is toxic because it binds to ATP synthase. <4> Uncoupling agents inhibit ATP synthase.
Output (English): chemistry
