A typical neuron at rest:
Correct answer: A. Is more positive outside than inside
- A. Is more positive outside than inside
- B. Is more negative outside than inside
- C. Has no charge on either side
- D. Has an equal charge on either side
Explanation
Option [A] A typical neuron is more positive outside than inside due to the presence of Na+ K+ pump which countertransports 3Na+ outside and 2K+ inside, removing one extra positive charge outside every time movement occurs.Option[B] At rest neuron is more positive outsideOption [c] Counter-transports of ions occurs in an unequal amount resulting in chargesOption[D] 3 Na+ move outside and 2K+ inside via sodium-potassium pump therefore unequal charge on either side
