Fluxes of H+ and K+ in Corn Roots

We report here on an experimental system that utilizes ion-selective microelectrodes to measure the electrochemical potential gradients for. H+ and K+ ions 







Ionic compounds are compounds composed of ions charged

Metal + Polyatomic ion ? ionic compound (usually). Nonmetal + Nonmetal ? covalent K+ potassium ion. Ba. Ba2+ barium ion. Cs. Cs+ cesium ion.



Interaction of K+ ion with the solvated gramicidin A transmembrane

profile of the K+ ion in the GA channel is obtained by analyzing iso-energy maps. Using Monte Carlo simulations the energy profiles of the K+ ion with the 



Differential ion dehydration energetics explains selectivity in the non

constriction but ion flow is assisted by a favorable electrostatic field generated by accommodate K+ ions and thus we assigned it as a closed state.

Outlook on K-Ion Batteries

The critical challenge for K-ion batteries is the development of an electrolyte compatible with both the graphite anode and high-voltage K-ion cathode and.

  • Quel est l'ion K+ ?

    Les ions du potassium en solution aqueuse
    Les ions potassium, de formule K+, sont des ions monoatomiques positifs, aussi appelés cations, portant une charge excédentaire positive. Il s'agit de la forme la plus courante sous laquelle se présente le potassium dans la nature.

  • Quel est le rôle de la pompe Na +/ K+ ?

    La pompe sodium-potassium ou Na+-K+ ATPase est une protéine transmembranaire hétérotétramère dont l'activité enzymatique utilise l'énergie issue de la dégradation de l'ATP en ADP et phosphate inorganique pour transporter des ions potassium et sodium contre leur gradient de concentration.

  • Quel est le nombre de charges positives du cation K+ ?

    Les ions potassium portent une charge +1 et les ions chlorure une charge ?1. La matière étant électriquement neutre, il y a autant d'ions chlorure que d'ions potassium.
  • L'insuline stimule un échangeur Na+/H+ électroneutre responsable d'une augmentation du sodium intracellulaire, augmentation qui stimule à son tour la Na+/K+-ATPase qui internalise le potassium (2K+) et expulse du sodium hors de la cellule (3Na+) [4], générant ainsi un gradient électrique transmembranaire.
