how is coenzyme Q10 related to Ubiquitin?

Co-enzyme Q10, Ubiquinone and Ubiquitin are all synonyms, apparently.

CoQ10/ubiquinone is an electron-carrying quinone which is involved in
the respiratory chain. it is not a protein.

ubiquitin is NOT the same. it is a small 79-residue protein with
multiple functions (i would argue that its main function is targeting
of proteins to the proteosome for degradation)

i'm not sure if they have any relation at all. perhaps olsen can shed
more light on the situation?

recent studies re: ubiquitin and proteasome pathways mention coenzyme
Q10 (ubiquinone).  these are all found in the miotchondria--ubiuitin
and proteasome pathway act as disposal system of degraded proteins and
coq10 acts both in production of ATP and as an antioxidant.  what role
does coq10 play in any function of the ubiquitin-proteasome protein
selection/degradation?
