The concentration of sodium is usually higher on the inside of neurons, compared to
outside. Sodium will move outside of neurons through the assistance of a small
protein in the neuron cell membrane. What type of transport is needed for sodium to
move outside of neurons?
Answers
Sorry I guess the some confusion
As during resting phase of neuron sodium ion are concentrated outside of cell.
when neuron is stimulated it cause can in the potential gradient as sodium ions moves inside the cell membrane it's called Depolarization
A process called Repolarization occurs also Depolarization in which sodium ions which were concentrated on the inner side of the nerve membrane moved out with help of a protein gated channel called sodium - potassium exchange pump which require ATP to work.
Its through out 3 sodium ions in exchange of 2 potassium ions that is it moves 3 sodium ions outside and moves 2 potassium ions inside of nerve membrane
Hope it will help you out.

Answer:
A polarized neuron in its resting state has A. high potassium & high sodium ion concentratio...
A polarized neuron in its resting state has A. high potassium & high sodium ion concentratio inside the cell membrane B. High potassium ion concentration on the outside of the cell membrane and high sodium ion concentration on the inside of the cell membrane C. High sodium and high potassium ion concentrations outside the cell membrane D. high sodium and high potassium ion concentrations outside the cell membrane
