CoQ is not fuel in the sense that it is consumed during cellular respiration, but it does help to shuttle excited electrons between enzymes complexes during electron transport. This is where the "fuel" that food is for our bodies is nearly done being converted into the energy in the bonds in ATP, but fuels are consumed in this process. As a nutritional supplement, CoQ can help provide enough material to keep cellular respiration running at peak efficiency.

Work Step by Step

Here, you are asked to find and review the role of CoQ in cellular respiration (see text and figures on electron transport). You will see that it helps use fuel but is not fuel itself, and you will be able to review its role in cellular respiration/electron transport.
