And since we have two acetyl coenzyme A molecules produced from one glucose, the breakdown of a single glucose basically leads to the production of six NADH, two Fadh twos and two GTPs, which is basically two multiplied by these quantities that we discussed earlier. Now, in the same way that the production of ATP and glycolysis takes place via substrate level phosphorylation producing our GTP, our Guanosine triphosphate and then ATP from the GCP takes place via the substrate level phosphorylation. Now let's move on to the electron transport chain. Now, the electron transport chain is basically a series of protein complexes that are found on the inner membrane of the mitochondria. And what happens is the NADH molecules and the Fad H two molecules basically transport or transfer the electrons onto our electron transport chain. And these electrons basically eventually end up reducing oxygen and forming water.
