But we're not done here, because this fadh two. And the next step is used to actually transfer those two electrons onto the NAD. And so we have two electrons, and a single H atom goes onto the NAD to form NADH. And the other remaining h ion no longer contains electrons. So it's simply H ion, and we form the H plus as well as the fad. Now, this step is interesting because it's unlike other steps that take place inside our body, because usually it's the NAD that is used to transfer electrons onto the Sad, but in this case, it's in reverse.
