What are the number of Na+ ions pumped out, and K+ ions pumped into the cell, with respect to the Na+ - K+ pump?
The axoplasm inside the axon contains high concentration of (i) ions and low concentration of _(ii)_ ions, during the resting state of the neuron.
What is the average potential difference across the nerve cell membrane?
Identify the value of action potential.
During resting potential, the axonal membrane is polarised, indicate the movement of +ve and –ve ions leading to polarisation diagrammatically.
The electronegativity inside the membrane is due to
