Ligand-Gated Channels

Outline by Shelby Pickett and Avalon Marker

Ligand Gated Channels

• Ionotropic receptors.
• Ligand-gated Calcium Channels
  • There are no ligand-gated channels specifically for Ca, though nicotinic ACh receptors, 5-HT3 receptors, and all types of glutamate receptors are known as non-selective cation channels, which allow flow of Na, K, Ca, and other cations. While ACh and 5-HT3 receptors allow mostly Na & K to pass, glutamate receptors allow a significant amount of Ca to pass through.
