molecules for the cell

Mitochondria

Explanation:

As monomers(e.g. glucose,galactose...) pass through cell membrane mitochondria takes them and breaks them down, when it breaks down the monomers, energies hidden in the monomers releases.

Later, when needed, other cells break down to use the energy inside the ATP which is produced by mitochondria.
