Large molecules enter the cell by endocytosis and exit the cell by exocytosis. Structure “A” facilitates, or helps, the diffusio
n of glucose across the membrane. In facilitated diffusion, molecules that cannot directly diffuse across the membrane pass through structure “A”.
A. Facilitated diffusion does not require any use of cell’s energy.
B. Osmosis through structure “A” requires use of the cell’s energy
C. Active transport through structure “A” does not require use of the cell’s energy.
D. Diffusion through structure “A” requires energy.
