Concept 5.1: Cellular membranes are fluid mosaics of lipids and proteins

proteins

What are not distributed evenly throughout the membrane? Answer with a single words or term.

molecular structure

The ________ shelters the hydrophobic tails of the phospholipids from water while it exposes the hydrophobic heads to the water.

abundant lipids

Lipids and proteins are the primary ingredients of cellular membranes even though carbohydrates play an important role. The most ________ are phospholipids.

membrane

A(n) ________ is held together by hydrophobic interactions, which are weaker than covalent bonds.

membrane proteins

Some ________ move in a highly directed manner along the cytoskeletal fibers by motor proteins.

presence of a phospholipid bilayer

The ________ represents a boundary between 2 aqueous compartments because of the molecular arrangement.

Proteins

What are much larger than phospholipids and move more slowly through the membrane? Answer with a single words or term.
