Question

When a neuron is not conducting any impulse i.e. it is at
resting stage, the axonal membrane show following events
except
1)Permeability for Kions
2)Nearly impermeable for Na ions
3)Impermeability for negatively charged proteins
4)Active transport of 2Nat outside for 3K+ into the
cell​

Answer 1

Answer:

Resting membrane is the condition in which there is no propagation of impulse. As the impulse passes from one part of the neuron to other the conductivity of the ions in the previous part decreases and the ion channels start closing. During this stage, k+ ion channels are opened as they slow workers and also called as lazy channels. They take more time to close and hence they remain open. Na+ channels are closed as the impulse passes off. Due to the presence of opened k+ channels, the permeability of k+ is more and as the na+ channels are closed the membrane is impermeable to na+. So the resting membrane of axon have more k+ inside and more na+ outside.
