What is depolorization?

Answer 1

Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.

Answer 2

Depolarization refers to a change in the electrical charge within a cell where the inside of the cell becomes less negative compared to the outside. In the context of neurons, depolarization is a key step in generating an action potential, which is essential for transmitting electrical signals along the nerve cell.
