And this prosthetic group contains the same isoloxazine ring that we find on the fad molecule. So the fad is similar to FMN in the sense that they contain the same three member ring that is used to actually form that or actually use ticketstrack and collect those electrons. Now, once we reform the NAD plus, that NAD plus can be reused by the process of the citric acid cycle, or Glycolysis, where the NAD plus molecules are needed to actually oxidize the glucose derivative and abstract those electrons. But what happens to the electrons once they are abstracted by FMM? Well, once the electrons are abstracted by FMN, those electrons begin to move along a series of other groups known as iron sulfur clusters, iron sulfur groups. And as these electrons actually move along these different groups we know from basic physics that whenever electrons flow along a certain area, that flow of electrons is what we call an electric current.
