Why do cells contain both macromolecules and small carbon compounds

For the Proper functioning -cells contain both macromolecules and small carbon compounds

Explanation:

Macromolecules are needed for the structural components of the cell membrane and all enzymes present in the cell are considered as a macromolecules that are required for all biochemical reaction occurring in the mitochondria.

carbon is the organic molecules is required by the cells for the regeneration of energy and when it is in monomer structure such as amino acid in the cytosol for the synthesis proteins.

Hence to function properly cell contain both macromolecules and small carbon compounds.
