receptor's
Binding site's characteristic
Receptor's is the possessive form of receptor, a structure that receives and responds to signals.
In biology, receptors are proteins on or in cells that bind to specific molecules—hormones, neurotransmitters, drugs—and trigger a response: The receptor's sensitivity determines how strongly the cell reacts.
Sensory receptors detect stimuli like light, sound, or touch.
