What's the significance of equilibrium potential?
Posted July 3, 2024

Answer

Equilibrium potential is significant because it helps determine the direction and magnitude of ion movement when channels for that ion open. A positive equilibrium potential is necessary to prevent Sodium (Na+) ions from the extracellular fluid entering the cell. Conversely, a negative equilibrium potential is necessary to prevent K+ ions from leaving the cell and to stop Chloride (Cl-) ions from entering the cell.
