Biological Function
ETQ-QO links the oxidation of fatty acids and some amino acids to oxidative phosphorylation in the mitochondria. Specifically, it catalyzes the transfer of electrons from electron transferring flavoprotein (ETF) to ubiquinone, reducing it to ubiquinol. The entire sequence of transfer reactions is as follows:
Acyl-CoA → Acyl-CoA dehydrogenase → ETF → ETF-QO → UQ → Complex III.

Famous quotes containing the words biological and/or function:
“I am fifty-two years of age. I am a bishop in the Anglican Church, and a few people might be constrained to say that I was reasonably responsible. In the land of my birth I cannot vote, whereas a young person of eighteen can vote. And why? Because he or she possesses that wonderful biological attribute—a white skin.”
—Desmond Tutu (b. 1931)
“Think of the tools in a tool-box: there is a hammer, pliers, a saw, a screwdriver, a rule, a glue-pot, nails and screws.—The function of words are as diverse as the functions of these objects.”
—Ludwig Wittgenstein (1889–1951)
