In voltage-gated ion channels, the channel conductance is a function of both time and voltage ( in the figure), while in leak channels, , it is a constant ( in the figure). The current generated by ion pumps is dependent on the ionic species specific to that pump. The following sections will describe these formulations in more detail. Using a series of voltage clamp experiments and by varying extracellular sodium and potassium … Nettet2.
