Question

We performed a lab on the "Effect of Molecular Weight and Lipid Solubility on Membrane Permeability"

Base on the information on the table please answer the following questions:

1. Which factor (molecular weight or lipid solubility) appears to be the most important in the diffusion of each alcohol across the membrane?

2. Which alcohol diffuses more rapidly?

3. Was either of these alcohol solutions isotonic to the RBCs (Red Blood Cells)? Iso-osmotic to RBCs? If so, Which one(s)?

Please explain your answers. Thanks!!!
