Definition
Reception is when a signal molecule binds to a receptor protein on or within the target cell, initiating transduction pathways that lead to cellular responses.
A protein molecule usually found embedded within plasma membrane surface of a cell that receives chemical signals from outside the cell.
G-Protein Coupled Receptors (GPCRs): These are large family of proteins that act as receptors for part of many different signaling pathways within cells. They play roles in many different physiological functions.
These are a type of membrane receptor that can open or close in response to the binding of a signaling molecule, allowing or blocking the flow of specific ions.
