Na+ - K+ ATPase pump is important for
Correct answer: C. Recovery of resting potential
- A. Maintenance of resting membrane potential
- B. Massive out flux of K+ after depolarization
- C. Recovery of resting potential
- D. Conversion of resting potential to action potential
Explanation
Na,K-ATPase maintains the proper concentration gradients of Na+ and K+. It is important that Na,K-ATPase stabilizes the resting membrane potential. If the resting membrane potential of nerve cells is not stabilized, nerve cells may fire when not needed or may not fire at all.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
