A : In the nervous system generation of action potential depends upon influx of sodium ion into axoplasm.
R : Influx of sodium ion during nerve impulse generation is due to efflux of potassium ions .

Which of the following ion moves first during the generation of an action potential along the axon?

Which of the following ion moves first during the generation of an action potential along the axon?

Action potential in neurons is generated by a rapid influx of ?

Assertion (A): Action potential is generated due to the exit of sodium ions from the neuron through the plasma membrane. Reason (R): Movement of sodium ions through the plasma membrane takes place under the influence of a stimulus.

Depolarisation of nerve membrane takes place through influx of ….. Ions

Influx of K^(+) inos into guard cells and efflux of H^(+) ions from guard cells lead to
