Question

Discuss what would happen if the ability of potassium ion to go through the membrane during the action potential were hindered, including the qualitative effect on the model electric circuit.

Answer 1

At the time of action potential the sodium ions enters the membrane by their respective channels so there is depolarisation and then to go back to its previous position ( polarised condition) the neurones potassium channels get opened and positive charge to compensate the entry of sodium charge goes out of the membrane..

So if this movement is hindered then the cell cannot get it's resting membrane potential as polarisation is hindered. So in future no depolarization will occur. No action potential can be generated in that cell.
