What are ion channels

What are ion channels? 

Ion channels, formed from membrane-spanning proteins, allow the selective and rapid flux of ions across cell membranes.

Channels respond to (are gated by) specific stimuli.

What are the types of ion channels?

  • Voltage-gated channels—activated by changes in the transmembrane voltage gradient
  • Ligand-gated channels—activated by binding of chemical agonists
  • Mechanical stretch or pressure
