Measurements of Electrical Potentials and Ion Fluxes
Experimental technics are described which permit the measurements of stable electrical potential differences across the cell membrane of single renal tubule cells and across single tubules. The inside of the tubule lumen is normally found to be electrically negative to the outside, while the cell interior is found to be negative to both the peritubular fluid and the tubule lumen. Such electrica...
متن کاملIon-diffusion potentials and electrical rectification across lipid membranes activated by excitation-induced material.
Membranes synthesized from sphingomyelin-tocopherol mixtures and treated with the protein, "excitation-inducing material," to increase their electrical conductance were tested for applicability of the Nernst equation and changes in electrical rectifying behavior with temperature. Above pH 7, and in the temperature range 303-323 degrees K, ion-diffusion potentials created by salts of monovalent ...
متن کاملIon transport in the gut.
The in vitro preparation of the small intestine of the rat is well suited for studies of ion transport. Data from this preparation indicate that the passage of water and electro-lytes across the intestinal epithelium depends on active transport. Glycolysis seems to be involved as a source of energy for the transport of ions from the mucosal to the serosal aspect of the intestinal wall. LITERATU...
متن کاملa comparative pragmatic analysis of the speech act of “disagreement” across english and persian
the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...
15 صفحه اولVacuolar and Cytoplasmic Potassium Concentrations in Pea Roots in Relation to Cell-to-Medium Electrical Potentials.
The cause of the cell-to-medium electrical potentials of plant and animal cells is incompletely understood. In some cases, the potentials appear to be diffusion potentials in which potassium ions play a major role (3,7.) This is indicated A) by potentials which are close to the Nernst potentials for potassium and B) by cell-to-medium potentials which become markedly less negative when the exter...
