Do non-enzyme catalysed reaction pathways exist?

Question

Can their be a kind of chemical reaction pathway in a cell, that is catalyzed or regulated but NOT necessarily by enzymes? I could not find anything on Google.I have almost no background in biology, and am only studying certain topics from a mathematical perspective.

Answer 1

All of the known chemical reaction pathways involve enzymes. However, this does not mean that none exist. Only that none have been found.
