We remove two electrons and we place those two electrons onto this electron accepted a flavin adenine dinucleotide molecule. So we reduce the Fad into Fadh two. And once we reduce the Fad into the Fadh Two, those two electrons are then transferred from the Fadh Two and onto another Flavon protein molecule known as the electron transferring flavor protein. 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.
