Question
Does the membrane potential increase or decrease? 5. A group of cells in the body have a resting membrane potential of -65 mV. When a signal opens non-specific cation channels in the cell membranes, the amount of Na* entering the cells (Na" influx) is greater than the amount of K* leaving the cells (K eflux). The ECF and ICF concentrations of Na+ and K+ are shown in the table below. Explain what causes net entry of Na+.
