If: membrane potential=-70mV, ENa=+60mV, and Ek=-90mV, consider which directions + Na and K+ will leak across the membrane. If both ions are crossing the membrane, what is the most important factor in determining whether membrane potential will become more positive or more negative? The relative permeability of the membrane to each ion. O How hard the Nat/K+-ATPase is working. O The synthesis of large negatively charged proteins inside the cell. O The day of the week.
