WebbThe protonmotive force generated during substrate oxidation is not used exclusively to drive ATP synthesis. Some protons “leak” back across the mitochondrial inner … Webb26 mars 2016 · The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it. Basically, this causes the cell to act like a tiny battery. Its energy can either be used right …
