Tracing a Ligand from Binding to Cellular Response
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
This capstone traces one signaling molecule from the moment it binds its receptor through second-messenger propagation to a specific cellular response and the signal's eventual termination.
Watch for
A single bound ligand produces a cellular response only because each downstream step amplifies and relays it — no single link in this chain acts alone.
