In the next step, we have the five carbon component that again undergoes an oxidation reduction reaction in which we generate a CO2 molecule and an NADH molecule. So again, two electrons are abstracted and collected by the NAD plus molecule to form these two molecules. And we form the four carbon intermediate C four. 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.
