Cell signaling which is a part of a complex communication process involves three stages: Reception, Transduction and Response.
Reception is the first stage of cell signaling in which signal molecule is detected and binded to a receptor protein positioned outside the target cell.
Transduction is the second stage that follows after the binding of the signal molecule, which triggers the receptor protein of the target cell to initiate transduction.
Response is the final stage in which the transduced signal, following the binding of the signal molecule, eventually generates a specific cellular response.
