WebWhat can diffuse through a semipermeable membrane? The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids. WebThe ability of a molecule to cross a membrane depends on concentration, charge and size. Molecules diffuse across membranes from high concentration to low concentration. Cell membranes prevent large charged molecules from entering cells without electrical potential.
