Question

A change in membrane permeability or ion concentration will change the resting membrane potential.

Answer 1

Answer:

True

Explanation:

Resting membrane potential is dependent on the following two factors –  

a) Concentration of ions –  When a neuron is in a resting position, sodium and potassium gradients develop. When an ion moves because of this gradient , resting potential is created. Any change in the ion concentration will change the concentration gradient which eventually will change the resting membrane potential.  

b) Membrane permeability – The membrane is more permeable to the potassium ion as compared to the sodium ion, thus the resting membrane potential is more inclined towards the equilibrium potential of potassium .  

 

Answer 2

It is true that a change in membrane permeability or ion concentration will change the resting membrane potential. A resting neuron has a voltage across its membrane called the resting membrane potential. The resting potential is determined by the concentration gradient of ions across the membrane and by membrane permeability to each type of ion. In aresting neuron, there are concentrations gradients across the membrane for Na+ and K+. Ions move down their gradients via channels, leading to a separation of charge that ceates the resting potential.
