column a
1 cholesterol
2 phospholipids
3 membrane protein
4 membrane carbohydrates
column b
a b
b a
c c
d d

Explanation:

1. Cholesterol is a small molecule that fits between phospholipids in the membrane. In the diagram, \(D\) represents cholesterol.
2. Phospholipids form the bilayer structure of the membrane. In the diagram, \(A\) represents phospholipids.
3. Membrane proteins are embedded in or associated with the membrane. In the diagram, \(B\) represents membrane proteins.
4. Membrane carbohydrates are often attached to proteins or lipids on the extracellular side of the membrane. In the diagram, \(C\) represents membrane carbohydrates.
