Which of the following will restore original ion gradients and RMP after hyperpolarization in neurons?
Correct answer: B. Na+/K+ pumps
- A. K+ channels
- B. Na+/K+ pumps
- C. Na+ channels
- D. Ca2+ channels
Explanation
In neurolemma, a specialized ATP dependant Na+/K+ pump is present which will restore original ion gradient and hence the resting membrane potential.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
