A prolonged increase in the permeability of the membrane to sodium ions would interfere with a neuron's ability to have an action potential.

Question

A prolonged increase in the permeability of the membrane to sodium ions would interfere with a neuron's ability to have an action potential.​

Quizplus · Accepted Answer

A neuron's action potential relies on the influx of sodium ions into the cell, which causes a depolarization of the membrane. If there is prolonged increase in the permeability of the membrane to sodium ions, it can result in a constant influx of sodium ions and prevent the membrane from repolarizing properly, which interferes with the neuron's ability to generate an action potential.
