And that basically is the ETF that we have here. So the two electrons are taken from that acetyl coenzyme A molecule and placed onto Fad to form the Fadh two. Then those electrons move onto another flavor protein molecule, ETF electron transferring flavor protein. Then those electrons move on to a different enzyme known as ETF dehydrone. So this basically contains sulfur ion groups or iron sulfur groups, and they can accept those electrons. And finally, those electrons are ultimately transferred onto Ubiquinone, which is found on the inner membrane of the mitochondria, and that reduces that Ubiquinone into Ubiquinol.
