Which ONE of the following statements about the resting membrane potential of a neuron is NOT CORRECT?单项选择题

A

The Na⁺/K⁺‑ATPase is essential for the immediate generation of the resting membrane potential by directly creating most of the voltage difference across the membrane.

B

The resting membrane potential arises primarily from the unequal distribution of ions across the membrane combined with selective permeability to potassium ions.

C

Potassium leak channels allow K⁺ to move down its electrochemical gradient, leaving behind negative charge inside the cell.

D

If the membrane suddenly became equally permeable to Na⁺ and K⁺, the membrane potential would move closer to 0 mV.
