Question
The openings in the membrane are not large enough to allow glucose to move through to solution A. Students are discussing how they could allow glucose to move by diffusion.
Which of the following could the students do to allow the movement of glucose?
Use a chemical to break glucose down into carbon, hydrogen and oxygen atoms.
Make the membrane pores smaller so that glucose would block the movement of water.
Add a protein molecule onto the membrane that is large enough to allow the transport of glucose.
Make the membrane completely solid so water cannot move.

To allow the movement of glucose by diffusion through the membrane, the students could:
**Add a protein molecule onto the membrane that is large enough to allow the transport of glucose.**
This approach would allow glucose to pass through the membrane via facilitated diffusion, utilizing specific transport proteins. The other options would not effectively facilitate glucose diffusion. For example, breaking glucose down into its atoms would not allow glucose to move as a whole molecule, and making the pores smaller would restrict movement rather than facilitate it. Making the membrane solid would prevent any movement, including that of water.
