Now, in the next year's of steps, we essentially transform this four carbon molecule back into oxyloacetate. In the process, we generate a high energy GTP molecule and NADH molecule as well as the fadh two molecules. So essentially four electrons are released here, two of these electrons are picked up by NAD and the other two electrons are picked up by the fad molecule. So again, nicotine amide adenine dinucleotide and fad is flavin adenine dinucleotide. And so because this takes place twice, because we have two Pyruvate molecules entering the mitochondria, we produce two, four, six nadhs, two fadh twos and two GCP molecules. And we also form two and two.
