Potassium ions are the most diffusible ion in the membrane potential because of the presence of leak channels that allow potassium to move easily across the membrane. This creates a concentration gradient that drives the movement of potassium ions into and out of the cell to establish the resting membrane potential.

Electric potential energy of an ion?

The electric potential energy of an ion is the energy stored in the electric field surrounding the ion due to its charge. It is directly proportional to the ion's charge and the electric potential at the location of the ion. This energy can be calculated using the formula: U = qV, where U is the electric potential energy, q is the charge of the ion, and V is the electric potential at that point.


What is nernst potential-?

The Nernst potential refers to the reversal potential of the membrane potential at which there is no net flow of a particular number of ion from one side of the membrane to another.


Who is equation is used to calculate equilibrium potential for a particular ion?

The Nernst equation is used to calculate the equilibrium potential for a particular ion. It takes into account the ion concentrations inside and outside the cell, as well as the charge of the ion, to determine the membrane potential at which there is no net movement of that particular ion across the membrane.
