Question

Sugars are large, hydrophilic molecules that are important energy sources for cells. how can they enter cells from an environment with a very high concentration of sugar?

Answer 1

The correct answer is by facilitated diffusion.  

The procedure of continuous passive transport of ions or molecules through a semi-permeable membrane with the help of particular transmembrane integral proteins is known as facilitated or passive-mediated transport or facilitated diffusion.  

It is a modification of osmosis incorporating a proteinaceous channel via which an extracellular solute can enter a cell in the absence of energy.
