Answer:
Leak sodium channels.
Explanation:
In the membrane of a neuron said to be at rest, potassium and sodium take different form with the voltage involved in its equilibrium. Because of the fact that they are charged, ions can't pass directly through the hydrophobic lipid regions of the membrane. Instead, they have to use specialized channel proteins that provide a tunnel across the membrane
Some ion channels are highly selective for one type of ion, but others let various kinds of ions pass through are called potassium channels, and ion channels that mainly allow to pass are called sodium channels.
