Permeation and transport

Membrane transport is the means by which small molecules and biopolymers permeate a cell membrane. Membranes are lipid bilayers exhibiting selective permeability, meaning that they are permeable to some substances and not to others. Membrane transport is mediated by membrane-transport proteins.
