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?

Question

Quizplus · Accepted Answer

Sugars are hydrophilic molecules, which means they cannot pass through the hydrophobic layer of the plasma membrane without assistance. Facilitated diffusion is the process of passive transport of these large molecules across the membrane through a protein channel or carrier protein. This allows the sugars to move down their concentration gradient from an area of high concentration outside the cell to an area of low concentration inside the cell.
