Receptor-ligand binding is a fundamental biochemical interaction where a ligand, such as a hormone or neurotransmitter, specifically binds to a receptor, triggering a cellular response. This interaction is critical for numerous physiological processes and is characterized by specificity, affinity, and reversibility, often governed by the principles of molecular recognition and signal transduction.
