The sodium channels consist of a highly processed α subunit associated with auxiliary β subunits. The system (Na+–K+)-ATPase, which maintains high intracellular K+ and low intracellular Na+, is localized in the plasma membrane, and belongs to the family of P-type ATPases, can also be ...
Here a nonlinear bidirectional model of a hair-cell is presented. Also developed are a canonical semi-state description for its Potassium and Sodium channels, and circuits suitable for a transistorized hardware implementation.Sellami, L.Kuan WongInstitute of Electric and Electronic Engineer...
Peptide neurotoxins targeting sodium (Na+) and potassium (K+) channels are two major components of scorpion venom for capturing prey (e.g., insects) and deterring competitors (e.g., small mammals). Although a great amount of information in terms of their sequences, structures and pharmacologic...
Sodium channels on skeletal muscle cell plasma membranes open and close in response to changes in voltage. a. True b. False The depolarization wave chases the repolarization wave down the length of the axon. (a) True (b) False. The intracellular fluid contains a lowe...
Tightly coupled models for the sodium and potassium conductance changes, in which the potassium "on" process is intimately related to the sodium "on" and "off" processes, are studied. It is shown that such coupled models are incapable of simultaneously showing the observed effects of conditioning...
Cell surface potassium ion (K+) channels regulate nutrient transport, cell migration and intercellular communication by controlling K+ permeability and are thought to be active only at the plasma membrane. Although these channels transit the trans-Golgi network, early and recycling endosomes, whether ...

It is used when alloyed with sodium as a cooling medium in nuclear reactors and its compounds are widely used, esp in fertilizers. Symbol: K; atomic no: 19; atomic wt: 39.0983; valency: 1; relative density: 0.862; melting pt: 63.71°C; boiling pt: 759°C [C19: New Latin potassa ...
UsesPotassium Chloride is a nutrient, dietary supplement, and gelling agent that exists as crystals or powder. it has a solubility of 1 g in 2.8 ml of water at 25°c and 1 g in 1.8 ml of boiling water. hydrochloric acid, and sodium chloride and magnesium chloride diminish its solubility...
The preclinical data obtained for COMPOUND A and COMPOUND B showed strong evidence that these drugs may not only block the delayed rectifier potassium current (IKr), but are also likely to interact with the sodium (INa) and calcium (ICaL) channels. No previous study at ion-channel level had...
