Detailed explanation-1: -Cell-surface receptors are transmembrane proteins that bind signal molecules in the extracellular space and generate different intracellular signals on the opposite side of the plasma membrane.

Detailed explanation-2: -Cellular receptors are proteins either inside a cell or on its surface which receive a signal.

Detailed explanation-3: -Intercellular joining Adjacent cells may have membrane proteins that connect in a range of different junctions. Gap junctions and tight junctions. This function helps cells to communicate with one another, and to transfer materials between one another.

Detailed explanation-4: -Membrane receptors transmit information about extracellular stimuli into the cytoplasm. This is achieved through a combination of changes in conformation and oligomeric state by membrane proteins with a single transmembrane domain (TMD).
