The major intracellular ion involved in polarization is potassium (K+). During the resting state of a cell, potassium ions are more concentrated inside the cell compared to the outside, contributing to the negative charge inside the cell relative to the outside. This difference in ion concentration is crucial for maintaining the resting membrane potential and is essential for the proper functioning of nerve and muscle cells during action potentials.

Main intracellular ion maintains icf osmotic pressure?
Potassium ions are the main intracellular ion that helps maintain osmotic pressure in the intracellular fluid (ICF). Potassium plays a crucial role in regulating cellular water content and facilitating proper cell function. Any imbalance in potassium levels can affect cell volume and disrupt normal cellular processes.
Is proteins the major intracellular anion?
No; the major intracellular anion is phosphate.
What is chief intracellular cation?
The chief intracellular cation is potassium (K+). It plays a vital role in maintaining cell function, including membrane potential and cellular signaling. Potassium is involved in various cellular processes such as muscle contraction and nerve transmission.
What is the chief positive intracellular ion in a resting neuron?
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.
What feature of a cation causes a chloride ion to become polarised?
The polarization of a chloride ion by a cation is primarily influenced by the charge density of the cation. Cations with a high charge and small size, such as ( \text{Li}^+ ) or ( \text{Mg}^{2+} ), exert a strong electric field, distorting the electron cloud of the chloride ion. This deformation results in a shift of the electron density within the chloride ion, making it polarizable. Consequently, the greater the charge density of the cation, the more pronounced the polarization effect on the chloride ion.

What is the preferred intracellular negative ion?
The preferred intracellular negative ion is chloride (Cl^-). It plays a crucial role in maintaining cell volume, regulating pH balance, and aiding in the transportation of molecules across cell membranes.
What is the concentration of sodium ions inside the cell is usually than the concentration of sodium ions outside the cell?
Extracellulary, Sodium is major ion. Intracellular concentration of sodium is: 12 mEq/L Extracellular concentration of sodium is: 140 mEq/L Intracellularly, Potassium is major ion. Intracellular concentration of Potassiumis: 140 mEq/L Extracellular concentration of Potassiumis: 3.5-5 mEq/L These concetrations are maintained by Na+/K+ ATPase.
Cross-bridge formation that results in muscle contraction requires intracellular?

What is the difference between electrical polarisation and dielectric polarisation?
in electric polarization ion is formed which have more tendency to form then magnetic polarization . in magnetic polarization just transfer of electron via flux . so the basic reason is that ion has more mobility constant then electron.so electric polarization is more faster then magnetic polarization.
What is the major anion in the extracellular fluids of the body?
Major Intracellular cation - K+ (Potassium) Major Extracellular cation - Na+ (Sodium) Major Intracellular anion - PO4+ (Phosphate) Major Extracellular anion - Cl- (Chloride)
