Answer 1

The specialized functions of different membranes are largely determined by the lipids they contain. Membrane lipids are hydrophilic and hydrophobic molecules, and all cell membranes have a lipid bilayer structure.

Step-by-step explanation:

The specialized functions of different membranes are largely determined by the lipids they contain. Membrane lipids are hydrophilic and hydrophobic molecules, composed of a hydrophilic portion and a hydrophobic portion. All cell membranes have the same lipid bilayer structure, with the hydrophilic heads of the phospholipids facing into the interior of the membrane and the hydrophobic tails on the outside. The most common lipids in most cell membranes are the phospholipids. The head group of a glycolipid is composed of sugars.
