Action - i) extracellular receptor (ii) intracellular receptor
Dear Student,
EXTRACELLULAR RECEPTORS
Extra cellular receptors are basically cell-surface receptors. they span the plasma mebrane and convert the extracelluar signals inot intracellular signals (Signal transuction) . These are embedded on the surface of the cells.
ACTION : There are three types:
The G-Protein linked receptor involves the activation of a G-protein upon ligand binding. This G-protein then either opens an ion channal or activates an enzyme.
The enzyme linked receptor has an intracellular domain. When a ligand binds to it, ot activates an enzyme, which sets of a series of reaction which causes the transfer of a signal.
INTRACELLULAR RECEPTORS
Intracellular receptors are those that are located inside the cell. The small and hydrophobic ligands enter the cell through the plasma membrane and reach its respective receptor. Upon binding , it releases a signal.
