What analogy can you create that compares to the structure of all four major macromolecules?

Basically, macro molecules  fall into four classes;
The lipids
The carbohydrates
The proteins
The nucleic acids
 The fact that their role revolve around energy production by carbohydrates, energy storage and insulation by lipids, storage of genetic material by nucleic acids and structural support by proteins means this can be equated to the executive arm of the government that deals in provision of social amenity, protection,  creation of job opportunities and sustaining a country's culture.

Bruh i don’t know the answer tbh but you can google it
