Vedclass · Answer

(A) The correct answer is $A$. When a neuron is not conducting any impulse (resting stage),the axonal membrane is comparatively more permeable to potassium ions $(K^+)$ and nearly impermeable to sodium ions $(Na^+)$. Additionally,the membrane is impermeable to negatively charged proteins present in the axoplasm. Consequently,the axoplasm inside the axon contains a high concentration of $K^+$ and negatively charged proteins,and a low concentration of $Na^+$. In contrast,the fluid outside the axon contains a low concentration of $K^+$ and a high concentration of $Na^+$,which establishes the concentration gradient.

In the resting stage of a neuron,the concentration gradient is generated due to:
