Quizplus · Accepted Answer

Sugars are large, hydrophilic molecules that cannot easily cross the hydrophobic lipid bilayer of cell membranes through simple diffusion. Facilitated diffusion, however, allows these molecules to enter cells with the help of specific transport proteins, without the expenditure of energy, following their concentration gradient from a region of high concentration to one of lower concentration.
