A stimulus has opened the voltage-gated sodium channel in an area of a neuron's plasma membrane. As a result, _______ rushes into the neuron and diffuses to adjacent areas; this in turn results in the ________ in the adjacent areas.
a. potassium / opening of voltage-gated potassium channels
b. sodium / opening of voltage-gated potassium channels
c. sodium / opening of voltage-gated sodium channels
d. sodium / closing of voltage-gated sodium channels
e. potassium / opening of voltage-gated sodium channels
c. sodium / opening of voltage-gated sodium channels

Sagot :

A stimulus has opened the voltage-gated sodium channel in an area of a neuron's plasma membrane. As a result, sodium rushes into the neuron and diffuses to adjacent areas; this in turn results in the opening of voltage-gated sodium channels in the adjacent areas. Thus, option "c" is correct.

When the potential in the membrane rises above the threshold energy, the natrium voltage-gated sodium channels will be opened. The opening of the natrium voltage-gated sodium channels will allow the movement of sodium to the cells. This happens because the concentration of sodium outside the cell is much higher than inside the cells, the sodium will flow into the cells.
