Highly lipid-soluble particles of any size can dissolve in the lipid bilayer and pass through the membrane.

Question

Quizplus · Accepted Answer

Highly lipid-soluble particles can easily dissolve in the lipid bilayer and pass through the membrane, regardless of their size. This is because the lipid bilayer is made up of nonpolar fatty acid chains that repel polar molecules but readily allow nonpolar molecules to pass through. Therefore, lipid-soluble molecules with high lipid solubility can easily dissolve in the lipid bilayer and pass through the membrane without requiring any energy or assistance from specialized transport proteins.
