What is the basic condition when a neuron is described as polarized?

A. There is a separation of positive and negative charges across a membrane.

B. Na+ is found outside of the neuron and K+ is found inside of the cell.

C. There are large, protein anions inside the neuron.

D. Na+ is found outside of the neuron.

Solution

Solution:
(A)The basic condition when a neuron is described as polarized is when there is a separation of positive and negative charges across a membrane.A neuron is said to be polarized when it is negatively charged intracellularly and positively charged extracellularly.This electrical difference between inside and outside of the cell(resting potential) is generated by sodium potassium pump.Na-K pump transfer more Na+ ion outside the neuron cell membrane and give rise to positive charge.And less number of K+ ions inside the cell membrane and create negative charge inside the neuron.
