Respuesta :
The action potential is produced by the movement of gated ion channels.
Explanation:
When an action potential or the nerve impulse moves down the 'axon', a change in polarity is observed in the axon's membrane. On receiving a signal from other neuron, the 'sodium' and 'potassium' gated ion channels start opening and closing as the membrane reaches the critical level to which a 'membrane potential' must be 'depolarized' to start an action potential.
Firstly, the sodium channels open up on the initiation of action potential, because of which sodium moves into the axon which results in depolarization. Secondly, re-polarization takes place as the 'potassium' channels open and 'potassium' moves away from the 'axon'. This brings about a change in polarity in the external and internal medium of the cell. Then, the nerve impulse moves down the axon in only one direction towards the axon terminal from where it sends signals to other neurons.
Action potential gets generated by the movement of ion channels. Thus option D is correct.
What is an Action potential ?
The action potential is a membrane potential that is seen when a specific cell location rises and falls. This takes space in several sorts of animal cells. Here the positively charged atoms move in and out of the channel. by the axon membrane. The neutron has a negative change related to outside the environment.
