Signal gated channel

WebIt is a ligand-gated Na + channel. (ligand-gated channels are channel proteins that open when a specific molecule (the ligand) binds to them) • The channel opens, and Na + enters the muscle cell, causing its membrane to depolarise. • This depolarisation causes voltage-gated Ca 2+ channels in the muscle cell membrane to open, leading to an ...
