Permeability through the lipid bilayer
A) Requires an input of metabolic energy
B) Saturates with higher concentration of solute
C) Always involves mo vem ent of solute from low to high osmotic pressure
D) Depends directly on the partition coefficient
E) Is increased by ionization of the solute

Question

Quizplus · Accepted Answer

Permeability through the lipid bilayer depends directly on the partition coefficient because substances that are more lipophilic (having a higher partition coefficient) can more easily diffuse through the lipid bilayer without the need for energy input, transport proteins, or moving against a concentration gradient.
