Below is a list of molecules with different chemical characteristics. knowing that all molecules will eventually diffuse across a phospholipid bilayer, select the option below that most accurately predicts the relative rates of diffusion of these molecules (fastest to slowest). alanine estrogen propanol sodium

The relative rates of diffusion of these molecules from the fastest to the slowest is; Estrogen, propanol, alanine, sodium
Phospholipid bilayer consists of two layers of phospholipids, with a hydrophobic, or water hating, interior and a hydrophilic, or water loving, exterior. This bilayer gives the cell membrane a property to allow selective movement of molecules in and out of the cell. Ions and larger polar molecules cannot pass through the lipid bilayer, passing of the molecule through the membrane depends on its size and its electrical nature.
