And at the same time, we basically reduce the Fad molecule into an Fadh two molecule. Now, this group, the Fad, is actually found bound to the acyl coenzyme a dehydrogenase. So this is a flavor protein dehydrogenase, and it's different. And it's different than the enzyme that catalyzes step one of the beto oxation process that we typically see in the matrix of the mitochondria. Now, this process doesn't stop here. Remember that in the matrix of the mitochondria, we generate that Fadh two molecule that then can be used by the electron transport chain.
