Answer :
K+ ions can readily exit the cell through K+ leak channels in accordance with the K+ concentration gradient created by pumps. Theoretically, these channels would allow K+ to enter the cell if there was a higher concentration of the ion outside the cell.
Do potassium channels that are leaky ever close?
While potassium leak channels enable potassium ions to permeate outside the cell, sodium leak channels further enhance the influx of sodium ions. The leak channels are constantly open, regardless of whether the neuron is at the resting membrane potential, depolarizing, repolarizing, or hyperpolarizing.
Ions can only travel through the membrane through a certain ion channel when it is open, according to an ion channel. The ion goes down its concentration gradient from high to low as a result of the ion channel opening; in this situation, K+ flows from the inside (intracellular area) to the outside (extracellular region).
