Question: Mitochondrial electronic transport and oxidative phosphorylation: 
 Options:  <1> They are two different processes, but coupled. Without electronic transport there will never be oxidative phosphorylation. <2> Without oxidative phosphorylation there can never be electronic transport. <3> The net yield of oxidative phosphorylation is about 2.5 moles of ATP per mole of FADH2. <4> Cyanide is toxic because it binds to ATP synthase. <5> Uncoupling agents inhibit ATP synthase.
