Lab: Diffusion Across a Semi-permeable Membrane

Question 27 • HVA 26-27 IM Biology A

If a test had been done of the solution inside the dialysis tube, what do you think the results would have been?

Answer
A
No glucose would be found because it all moved outside the tubing.
B
No glucose would be found because glucose was not placed inside the dialysis tube.
C
The glucose would be found because it would reach an equilibrium.

Explanation

Glucose molecules can pass through the dialysis tubing, so they diffuse from where their concentration is higher to where it is lower. Diffusion continues until glucose is distributed on both sides at equilibrium, meaning glucose would still be found inside the tube. Therefore, “The glucose would be found because it would reach an equilibrium” is correct.
