Sentence examples for membrane potential generated from inspiring English sources
Conjugation of the cell penetrating hepta-arginine vector to their N- or C-termini through two glycine residues resulted in more active peptides, which also permeabilized the red blood cells with a relatively high plasma membrane potential generated in the presence of valinomycin.
Initially, intracellular CLC's were thought off as Cl− channels facilitating acidification of the organellar lumen by providing an electrogenic shunt for the lumen-positive membrane potential generated by the V-type H+-pump [12].
We found a ∼50% reduction of membrane potential generated by oxidation of fatty acid (palmitoylcarnitine and octoylcarnitine) (Figure 3B), consistent with the observed decreases in state 3 O2 consumption with these substrates.
Fractions were incubated in a 200 µl final volume of a solution which is described in the figure legends (see below), plus 3 µM acridine orange for 3 min prior to the addition of 100 µM PPi or 0.5 mM ATP. Nigericin was used to collapse the membrane potential generated.
Membrane potential generated by the NDH-1 mutants was monitored optically using oxonol VI as reporter.
They are all associated with a decreased NADH-oxidation activity (40 98% of reduction), a partial CI disassembly and, in particular, the substitutions corresponding to p.E214K and p.Y215H abolished the membrane potential generated by the respiratory chain [26 28].
In contrast, the extra-mitochondrial localization of monomeric form of the dye, as a result of disrupted membrane potential, generates a signal of green fluorescence (39).
Dextromethorphan, which is a representative non-narcotic antitussive and has an inhibitory effect on GIRK channel activated currents [ 15], antagonized the 5-HT-induced hyperpolarization and depolarized the membrane potential, generating action potentials in dorsal raphe neurons.
Keratinocytes do not normally generate APs, but they do have resting membrane potentials generated by currents mediated by ion (e.g., K+, Cl−) channels intrinsic to the plasma membrane (Wohlrab et al., 2000).
The mitochondrial membrane potential is generated by the ETC and is essential for the synthesis of ATP by mitochondria.
Subsequently a membrane potential was generated by either an inward or outward directed potassium gradient.
