Question

Quizplus · Accepted Answer

A depolarizing graded potential is a type of potential that leads to a decrease in the membrane potential or makes the membrane less polarized. This is caused by the influx of positive ions such as Na+ and Ca2+ into the cell, which makes the inside more positive. This type of potential is typically seen when the cell is stimulated and approaches its threshold for firing an action potential.
