The primary purpose of the flow of electrons through the protein complexes in the inner mitochondrial membrane is to supply energy for the proton pump. This pump uses the energy from electron transport to pump protons across the inner membrane, creating a proton gradient that can be used to synthesize ATP through oxidative phosphorylation.
