Which of the following is not involved in creating the resting potential of a neuron?
A)diffusion of potassium ions out of the cell
B)diffusion of sodium ions into the cell
C)membrane permeability for sodium ions greater than potassium ions
D)membrane permeability for potassium ions greater than sodium ions
E)The interior of the plasma membrane has an excess of negative charges.

Question

Quizplus · Accepted Answer

The resting potential of a neuron is created by the balance of opposing forces of diffusion and electrostatic pressure on different ions across the cell membrane. Sodium and potassium ions play a crucial role in this process, with potassium ions diffusing out of the cell and creating a negative charge inside the cell. This is aided by the greater permeability of the membrane to potassium ions as compared to sodium ions. However, membrane permeability for sodium ions greater than potassium ions would actually make it more difficult to maintain the negative resting potential. Therefore, option C is not involved in creating the resting potential of a neuron.
