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.

Ion Channel Receptors:

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.
