, CELL – SURFACE RECEPTORS
•Cell-surface receptors also known as transmebrane receptors, are
proteins that are found attached to the plasma membrane .
•These receptors bind to external ligand molecules because ligands do not

travel across the membrane .
MZO2104
•This type of receptors spans the plasma membrene and performs signal
transduction , in which an extracellular signal is converted into an
intracellular signal .
•Cell – surface receptors are also called cell – specific proteins or markers
because they are specific to individual cell types.
•Ligands are hyrophilic and lipophilic both .
