The Equilibrium Potential of Sodium Is

Question

The equilibrium potential of sodium is
A) -90mV.
B) -65mV.
C) -70mV.
D) +30mV.
E) +66mV.

Accepted Answer

The equilibrium potential of sodium (Na+) is typically around +66mV, as calculated using the Nernst equation based on the concentration gradient of sodium ions across the cell membrane.
