The membrane of a resting neuron is much more permeable to which of the following ion than any other ion? A)Cl B)Ca²⁺ C)Na⁺ D)K⁺ E)H⁺

Question

Quizplus · Accepted Answer

The resting membrane potential of a neuron is around -70 mV, which is primarily determined by the balance of potassium ions (K+) inside and outside the cell. The membrane of a resting neuron is more permeable to K+ than any other ion. This is because the neuron typically has more K+ leakage channels than any other type of ion channel in its membrane. Therefore, option D is the best choice as it specifies K+ ion.
