Imagine a cell with no voltage gated Na+ or K+ channels, and for which the Na+ equilibrium potential (ENa) is -80mV. Intracellular and extracellular concentrations of Na+ and K+ are typical. If the plasma membrane were equally permeable to Na+ and K+, the membrane potential would be....

a) 0 mV.

b) closer to ENa than Ek.

c) closer to Ek than ENa.

d) about halfway between ENa and Ek.

e) undetermined because insufficient data are provided.
