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) slightly permeable to sodium ions
B) fully permeable to calcium ions
C) impermeable to sodium ions
D) highly permeable to chloride ions

Question

Quizplus · Accepted Answer
