During depolarisation voltage-gated sodium ion channels open due to an electric stimulus. As the sodium ions rush back into the cell, their positive charge changes potential inside the cell from negative to more positive. True False

Question

During depolarisation voltage-gated sodium ion channels open due to an electric stimulus. As the sodium ions rush back into the cell, their positive charge changes potential inside the cell from negative to more positive. True False

Answer 1

True.During depolarization, voltage-gated sodium channels open in response to an electrical stimulus. The influx of sodium ions (Na+) into the cell, due to their concentration gradient and the electrical potential difference, causes the membrane potential to become more positive, shifting from a negative resting state towards a positive value.
