What are the steps of the ETC?

1) Proton motive force = NADH + FADH2 oxidised to release electrons and protons electron energy used to pump h+ from matrix proton buildup in intermembrane space 2) ATP made with chemiosmosis of H+ with ATP synthase = made with ADP + Pi 3) oxygen reduced = removes de energized electrons and free protons to form water and maintain H+ gradient
