The permeability of a proteinfree lipid bilayer to various m

The permeability of a protein-free lipid bilayer to various molecules depends on their properties. Sort the following in order of low to high permeability from left to right. Your answer would be a six-digit number composed of digits 1 to 6, e.g. 123456. (NO SPACE BETWEEN NUMBERS) O_2 ATP RNA oligonucleotide Na^+ Glucose Urea

Solution

The smallest ones have high permeability and the complex large molecules have low permeability.

The membrane is highly permeable to lipid-soluble molecules and impermeable to water soluble molecules.
