Explanation:

Cell membranes are composed of a phospholipid - bilayer. Phospholipids have hydrophilic heads and hydrophobic tails. The tails face each other, creating a hydrophobic interior. Peripheral proteins, integral proteins, and glycoproteins are associated with the membrane but do not create the hydrophobic interior. Phospholipid heads are hydrophilic.
