When an anabolic pathway results in the splitting of a molecule, all of the resulting product molecules enter into other anabolic pathways.
In heterotrophic biochemistry, all pathway reactions generate product molecules that enter into anabolic pathways, enter into catabolic pathways, or are secreted.

Some degradation processes may compete with anabolic pathways
and may have to be regulated.
All anabolic pathways
have their origins in these five source nodes for the synthesis of the entire metabolome.
