Vedclass · Answer

(C) The resting membrane potential is generated due to the differential permeability of the axonal membrane to $K^+$ and $Na^+$ ions and the presence of negatively charged proteins inside the axoplasm.During the resting state,the axonal membrane is significantly more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.This leads to the efflux of $K^+$ ions,creating a negative charge inside the membrane.To maintain this unequal distribution of ions,neurons utilize metabolic energy in the form of $ATP$ (chemical energy),not electrical energy,via the $Na^+-K^+$ pump.Therefore,the Assertion is correct,but the Reason is incorrect.

$A$ : The imbalance in the concentration of $Na^+, K^+$ and proteins generates the resting potential.
$R$ : To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.
