Such a difference indicates a slower glucose diffusion in cancer tissues, which originate from their ability to trap far more glucose than healthy.
Whether a cell uses facilitated diffusion or active transport depends on the specific needs of the cell for example, the sugar glucose is transported by active . A glucose molecule is too large to pass through a cell membrane via simple diffusion instead, cells assist glucose diffusion through facilitated diffusion and two. Facilitated diffusion using carrier proteins or ion channels allows these important molecules (like glucose) to cross the membrane.
