Cell Biology
Receptor
A protein molecule that receives and responds to specific signals, typically located on cell surfaces or inside cells. Receptors enable cells to sense and respond to their environment.
Biological Context
Receptors bind specific molecules (ligands) like a lock and key. This binding triggers cellular responses: gene activation, enzyme release, electrical signals. Receptor sensitivity can be adjusted—upregulated when signals are weak, downregulated when overwhelmed.
Business Application
Business receptors: the people, systems, and processes that detect specific signals. Customer feedback systems, competitive intelligence, trend spotting. Receptor specificity determines what signals an organization can detect and respond to.
