More specifically in the macromolecules of the cells.
These macromolecules could either be amino acids, proteins or nucleic acids. They
are responsible for the chemical changes and reactions that affects largely the
cell and its composition. Take for instance the cytoplasm of the cell where
these organelles are settled. These simple organelles are composed of
macromolecules which ignites and catalyses different functions that enables
cells, in macro-perspective in motion and metabolism. In intestines for

compounds that are used and these nutrients delivered throughout the body and
again broken down by into smaller components.
