10 Questions
What is the term that identifies different types of communication methods between living cells?
Cellular Communication
What is the role of a ligand in cellular communication?
To bind to receptors on the target cell
What happens when a ligand binds to a receptor on the target cell?
A messenger molecule relays the signal to the target cell
What is the sequence of events in cellular communication?
Ligand is released, binds to receptor, messenger relays signal, cell responds
Why do only specific target cells respond to specific ligands?
Because only specific target cells have the specific receptor
What is the primary driving force for the flow of ions across the plasma membrane in ligand-gated ion channels?
The electrochemical gradient for the permeant ions
What is the role of the pore in ligand-gated ion channels?
To enable the regulated flow of selected ions across the plasma membrane
What happens to the ion channel when the ligand leaves the receptor?
The channel closes again
What is the function of ligand-gated ion channels in cellular communication?
To trigger a change in cell activity
What is an example of a ligand that can bind to a receptor on a target cell?
Acetylcholine
