What is the result of the electrons being passed on to O2 in the electron transport system?

Step-by-step solution

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.
