Abstract

The intracellular distribution of lipophilic ions and weak acids and bases was studied in intact hepatocytes as indicators of gradients of pH and membrane potential. Mitochondrial and plasma membrane potentials of 161 and 32.8 mV (negative inside), respectively, were calculated from the intracellular accumulation of triphenylmethylphosphonium (TPMP+) and thiocyanate in the intact hepatocyte, assuming a two-compartment model. The predominantly mitochondrial localization of TPMP+ was confirmed using disruption procedures that selectively break the plasma membrane but not the mitochondrial membrane. The intracellular distribution of 5,5-dimethyloxazolidine-2,4-dione and methylamine was studied with similar techniques. A cytosolic pH of 6.95 to 7.00 and a mitochondrial delta pH of 0.97 units was observed. From these results, a total mitochondrial protonmotive force in the intact cell in excess of -200 mV was obtained.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
