What ion is responsible for restoring the voltage difference across a neuron's plasma membrane?

Answer 1

The resting membrane potential of a neuron is largely determined by the sodium and potassium levels across the plasma membrane.

This is primarily regulated by the Sodium Potassium ATPase in the plasma membrane. The Na/K ATPase pumps out 3 sodiums for every 2 potassium ions pumped in. It is therefore electrogenic and makes the inside of the cell negative with respect to the outside.

Answer 2

in reality, intemembrane electronegativity is achieved again thanks to the work of a protein called¨Na/K ATPase ¨ in the cell membrane, wich pumps out the sodium and pumps in potassium.

Answer 3

sodium i think Na^+
