Solutions

Expert Solution

Answer: D.Potassium ions move out of the cell.

Explanation:

Because of the nervous system in the human body, bodily organs exchanging information between them. Action potentional in the nervous system will play key role in exchanging information. Initially energy in the nervous system will be in rest state then it is called resting potential. Whenever sensory information entered into the nervous system through senses, that resting potential will start functioning so that then it is called as action potential.

Rapid change in positive voltage and negative voltage will help action potential to pass through neurons so that information will be transferred. When sodium ions entered in the cell, the cell will be occupied by positive voltage and when potassium ions move out of the cell, the cell will be occupied by negative voltage. This process will happen fastly so that action potentional will move through nervous system.
