How is a proton gradient formed
WebHow is the proton gradient established? A. Water is hydrolyzed to oxygen and protons in the electron transport chain B. Energy released by the oxidation of NADH and FADH2 … 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…
