- The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
- At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.
<h3>At potassium's equilibrium potential, what happens?</h3>
- At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
- There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.
<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
- Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
- Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.
