Voltage-gated ion channels Pharmacology Education Project

WebIon channels are integral membrane proteins that contain pathways through which ions can flow. By shifting between closed and open conformational states ('gating' process), they control passive ion flow through the plasma membrane. Channels can be gated by membrane potential, or specific ligands, or other agents, such as mechanical stimuli. Web12 sep. 2024 · Ion channels control ion movement across the cell membrane because the phospholipid bilayer is impermeable to the charged atoms. When the channels are closed, no ions can move into or out of the cell. When ion channels open, however, then ions can move across the cell membrane.
