Question

What are the four carbon macromolecules the body uses and makes?

Answer 1

Living things are made of types of molecules, known as macromolecules.

There are four major classes of biological macromolecules:

carbohydrates

lipids

proteins

nucleic acids

Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
