WebJan 1, 1981 · The cytoplasmic membrane is the main borderline between the cytoplasm and the cell's surroundings. It forms a diffusion barrier through which most solutes can pass only via specific translocation systems. Energy-transducing systems, such as electron-transfer systems and the ATPase complex are also located in this cytoplasmic membrane. WebDec 24, 2024 · The material being transported is first attached to protein or glycoprotein receptors on the exterior surface of the plasma membrane. This allows the material that is needed by the cell to be removed from the extracellular fluid. The substances are then passed to specific integral proteins that facilitate their passage.
