Question

The permeability of a membrane to a particular solute is related to which two variables, and what is the relationship?

Answer 1

Answer;

-The permeability is directly proportional to lipid solubility and inversely proportional to the size of the molecule.

Explanation;

-The cell membrane’s lipid bilayer structure provides the first level of control. The phospholipids are tightly packed together, and the membrane has a hydrophobic interior. This structure causes the membrane to be selectively permeable.

-A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer.
