Question

The E_K for a cell is -90 mV and E_NA is + 55 mV. At a resting membrane potential of -70 mV and assuming conductances ONLY to Na⁺ and K⁺, A) There is an inward K⁺ curr ent B) There is an outward Na⁺ current C) g_Na > g_K D) The Na,K-ATPase pumps Na⁺ into and K⁺ ou t of the ce ll E) The total current across the membrane is zero

Quizplus · Accepted Answer

At resting membrane potential, the total current across the membrane is zero because the inward and outward currents are balanced.

The EK for a Cell Is -90 MV and ENA

The E_K for a Cell Is -90 MV and E_NA
