Channels that open or close in response to changes in the electrical charge or voltage across the plasma membrane are called

A) ligand-gated ion channels.
B) leak ion channels.
C) relegated ion channels.
D) voltage-gated ion channels.
E) obligated ion channels.

Voltage-gated Ion Channels

Proteins embedded in cell membranes that open or close in response to changes in membrane potential, crucial for the propagation of nerve impulses.

Plasma Membrane

A phospholipid bilayer that surrounds a cell, providing it with structural support and controlling the movement of substances into and out of the cell.

Electrical Charge

A fundamental property of particles that causes them to experience a force when placed in an electromagnetic field.
