The following steps in the respiratory process are to release and utilize the energy stored in NADH+H⁺ and FADH2. This is accomplished when they are oxidized through the electron transport system and the electrons are passed on to O₂ resulting in the formation of H₂O. The metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system (ETS) (Figure 12.4) and it is present in the inner mitochondrial membrane.
