Membrane structure and selective permeability

Membrane structure and selective permeability

Labelled fluid mosaic model showing phospholipid bilayer, hydrophilic heads, hydrophobic tails, channel protein, carrier protein, glycoprotein, glycolipid, cholesterol, oxygen crossing directly and sodium ion blocked A cell-surface membrane is a phospholipid bilayer with proteins, glycoproteins, glycolipids, and often cholesterol embedded in it. It is partially permeable, so its structure determines which substances cross easily.
