Question

The binding of a ligand to a receptor is important for allowing external signals to affect intracellular processes. Which property of receptor proteins is key for this signaling to occur?

Select one:

a. Non-reversible binding to ligand

b. Non-rigid structure that allows for conformational changes when a ligand binds

c. Non-specific interactions with extracellular molecules

d. Non-specific interactions with intracellular molecules

Answer 1

b. Non-rigid structure that allows for conformational changes when ligand binds.

( After ligand binding receptor make some conformational changes like loop out or phosphorylate or sometime cleaved at cytosolic side that help it for activation and downstream signalling.)
