284574 During the propagation of a nerve impulse, the action potential results from the movement of

1

K^{+}

ions from extracellular fluid to intracellular fluid

2

{Na}^{+}

ions from intracellular fluid to extracellular fluid

3

K^{+}

ions from intracellular fluid to extracellular fluid

4

{Na}^{+}

ions from extracellular fluid to intracellular fluid

Explanation:

D
During the propagation of nerve impulse when a stimulus of adequate strength is applied to a polarized membrane, the permeability of the membrane to ${Na}^{+}$ is greatly increased at the point of stimulation. As a result, the sodium ion channels permit the influx of ${Na}^{+}$ by diffusion. Since, there are more ${Na}^{+}$ ions entering than leaving, the electrical potential of the membrane change from $- 70 mV$ towards zero.

284575 Depolarization of axolemma during nerve conduction takes place because of:

1 Equal amount of

{Na}^{+} & K^{+}

move out across axolema

2

{Na}^{+}

move inside and

K^{+}

move more out side

3 More

Na +

outside

4 None
