Mitochondria are shown to form a conductive pathway throughout the cell in the form of a proton motive force, and throughout this network, mitochondrial protein localization seems to be varied, allowing optimized generation and utilization of the mitochondrial membrane potential; the rapid energy distribution network, which depends on conduction rather than diffusion, could explain how the muscle can rapidly respond to energy demands.
