Ligand Gated ion
Anthony and Physiological
| Question | Answer |
|---|---|
| What are Ligand Gated Ion Channels? | commly referred to as ionotropic receptors, and are transmembrane ion-channel proteins which open to allow ions to pass through the membrane in response to the binding of chemical messenger. |
| What happens when a presynaptic neuron is excited? | it releases a neurontrasmitter from vesicles into the synaptic cleft. |
| The neurotransmitter then binds receptors located on the______. | Postsynaptic Neuron |
| A transmembrane domain which includes the ion pore, and an extracellular domain which incldes the___________________. | Ligand Binding (an allosteric binding site. |
| What is the function of such receptors? | synapses |
| What are the three superfamilies that classifies the LICs, which lack evolutionary relationship? | Cys-Loop Receptors, Ionotropic Glutamate Receptors, and ATP-Gated Channels |
| What does postsynaptic neuron result in? | Depolarization and Hyperpolarization |
