(c)
When a neuron is not conducting any impulse, i.e., resting, the axonal membrane is comparatively more permeable to potassium ions (
) and nearly impermeable to sodium ions (
). Similarly, the membrane is impermeable to negatively charged proteins present in the axoplasm. Consequently, the axoplasm inside the axon contains high concentration of 
and negatively charged proteins and low concentration of 
. In contrast, the fluid outside the axon contains a low concentration of 
, a high concentration of 
and thus form a concentration gradient

c) |
Active transport of proteins |
