Although the membrane of a "resting" neuron is highly permeable to potassium ions, its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is also
A) fully permeable to sodium ions.
B) slightly permeable to sodium ions.
C) fully permeable to calcium ions.
D) impermeable to sodium ions.
E) highly permeable to chloride ions.

Question

Quizplus · Accepted Answer

The membrane of a "resting" neuron is slightly permeable to sodium ions, which can depolarize the neuron and prevent the membrane potential from exactly matching the equilibrium potential for potassium.
