This is the outer surface of the cell, that is to say, the continuous layer which separates the cytoplasm within the cell from the interstitial fluid outside it. The membrane itself is a four-layered molecular structure, namely a bimolecular lipid layer 'sandwiched' between two protein layers. Becau
