Hyperpolarization of the resting membrane potential due to o

Hyperpolarization of the resting membrane potential due to opening of potassium channels and efflux of intracellular potassium results from stimulation of

A: Beta adrenergic receptors

B: Muscarinic receptors

Solution

Answer is A

Beta adrinergic receptors.

It causes the efflux of potacium ions from cell there by causes hyperpolarisation.
