WebNo ion can directly pass through the cellular membrane. However, there are channels that are usually open that allow ions, such as potassium to pass. These are appropriately called leak channels. They are not voltage gated, so if you looked at their IV curves it’s essentially an ohmic (straight line) relationship. WebThe flow of ions through membrane channels is dependent on the establishment of ion gradients across the plasma membrane. All cells, including nerve and muscle, contain ion pumps (discussed in the next …
