How does fccp affect mitochondria potential
WebSep 2, 1997 · Oligomycin, an ATP synthase inhibitor, does not alter mitochondrial membrane potential and thus does not change calcium transport across the mitochondrial membrane . To determine the origin of the FCCP-stimulated increase in [Ca 2+ ] i , we measured the FCCP effect either in calcium-free Tyrode’s solution or in culture medium containing 0.4 ... WebThe protonmotive force (Deltap) across the mitochondrial inner membrane drives ATP synthesis. In addition, the energy stored in Deltap can be dissipated by proton leak through the inner membrane, contributing to basal metabolic rate and thermogenesis.
