FADH<sub>2</sub> thereby facilitates transfer of electrons to [[coenzyme Q]], an intermediate in the electron transfer chain.<ref name=[[Stryer]]>{{cite book |last= Berg |first=JM |coauthors= JL Tymoczko, L Stryer |title= Biochemistry - 5th Edition |pages =465-484, 498-501|publisher= WH Freeman and Company |year=2002 |isbn= 0-7167-4684-0}}</ref>
