Question

Opening of sodium channels in the membrane of a neuron results in __________.

Options:
A) Hyperpolarization
B) Repolarization
C) Depolarization
D) No change

Answer 1

The opening of sodium channels in the membrane of a neuron results in depolarization of the membrane.

Step-by-step explanation:

The opening of sodium channels in the membrane of a neuron results in depolarization of the membrane. During depolarization, sodium ions enter the cell, causing a decrease in the difference in voltage between the inside and outside of the neuron. This change in voltage is essential for generating and conducting nerve impulses.
