5 Questions
What type of proteins are ligand-gated ion channels?
Integral membrane proteins
What drives the flow of ions across the plasma membrane in ligand-gated ion channels?
Passive transport driven by the electrochemical gradient
What happens to the channel when the ligand binds to the receptor?
The channel opens
What is an example of a ligand that binds to a receptor and opens an ion channel?
