Answer: Option E) Facilitated diffusion
Explanation:
Facilitated diffusion engage selective transport proteins to move non-lipid soluble solutes like glucose across the lipid bilayer along concentration gradient (from high to low concentration) without the supply of energy (ATP).
Thus, transport proteins embedded in the lipid bilayer help move large quantities of glucose rapidly in intestinal cells by facilitated diffusion.
