Quizplus · Accepted Answer

A receptor is a protein molecule located on the surface or inside a cell. It binds to a hormone or other biologically active molecule, thereby initiating a cellular response. Receptors are highly specific for certain hormones or ligands and are essential for many cellular processes. Transmitters are molecules that transmit signals between nerve cells, while an active site is a specific region on an enzyme where the substrate binds. Target cells are cells that have a specific receptor for a particular hormone.
