Question

When a neuron is in resting state i.e., not conducting any impulse, the axonal membrane is:

A

equally permeable to both Na+ and K+ ions

B

impermeable to both Na+ and K+ ions

C

comparatively more permeable to K+ ions and nearly impermeable to Na+ ions

D

comparatively more permeable to Na+ ions and nearly impermeable to K+ ions

Step-by-Step Solution

when a neuron is not conducting any impulse (resting state), the axonal membrane is comparatively more permeable to potassium ions (K+) and nearly impermeable to sodium ions (Na+). This differential permeability helps maintain the concentration gradient required for the resting potential .

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Neural Control and Coordination. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
