And the Ubiquinol carries those two electrons onto the second proton pump found along the electron transport chain. And so we see that the Fadh two that is produced in this oxidation step basically generates 1.5 ATP molecules along the protons, along the proteins of the electron transport chain, etc. Now let's move on to step two. So step two is basically a hydration step, and it is catalyzed by an enzyme known as Enoil coenzyme hydrates. So we take this same product molecule, TransDelta Two, inoil coenzyme A. And now it acts as a reactant in this particular step.
