Which of the following statements is most accurate about the plasma membrane of excitable cells

Which of the following statements is most accurate about the plasma membrane of excitable cells (such as the squid giant axon used in the experiments illustrated in the online animations)?

The resting

membrane potential of neurons is explained by the “leakiness” of the plasma

membrane for the outward flux of sodium ions.

The resting

membrane potential of neurons is explained by the “leakiness” of the plasma

membrane for the inward flux of potassium ions.

The resting

membrane potential of neurons is explained by the electrogenic nature of the

sodium-potassium ATPase.
