Ketone group of the quinone structure-Coenzyme Q

Question

Coenzyme Q can act as an intermediate electron carrier, since the

ketone group of the quinone structure is readily reduced to an alcohol.

TRUE /FALSE

Answer 1

FALSE.

Coenzyme Q10 (also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ10, CoQ, Q10, or Q) is a benzoquinone, where Q refers to the quinone chemical group, and 10 refers to the isoprenyl chemical subunits.  Diagram in link.

Answer 2

umm... i would say this is true actually.     Coenzyme Q is also known as Ubiquinone   and does act as an intermediate electron carrier  from  comblex 3-4 of the electron transport chain.   actually it might be complex 1-3  but either way,   it does have 2 ketone groups which do get reduced down to alcohols (ubiquinol).          I would definitly argue true.
