"The generation of a transmembrane electrical potential through ion movement across a cell membrane drives biological processes like nerve conduction, muscle contraction, hormone secretion, and sensation. By convention, physiological voltages are measured relative to the extracellular region; a typical animal cell has an internal electrical potential of (−70)–(−50) mV. An electrochemical gradient is essential to mitochondrial oxidative phosphorylation. The final ste… " - How is a proton gradient formed
