Answer – D. Facilitated diffusion through protein channels
Glucose molecules are too big to pass through the plasma membrane by direct diffusion, so Glucose gains entrance into a cell by facilitated diffusion through protein channels in the plasma membrane. Since glucose moves with the concentration gradient, the built-in protein channels are only there to facilitate the movement of glucose into the cell and no energy is expended.
