Tracing a Ligand from Binding to Cellular Response
Captions available
The idea
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.
Where people slip
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.
