functions of the membrane correct answer: -the structure of the membrane is key for its function -act as a barrier regulating import and export of molecules -help with compartmentalization of the cell, creating particular environments for certain processes so multiple specialized processes could occur at once -modulates cell-cell recognition with their glycoproteins and glycolipids located on the outer leaflet facing the cytosol -signaling across the membrane by proteins and lipids p...
