So we have three NAD plus pick up three of these hydride ions to form three nadhs. But two of these electrons are picked up by another important carrier found in our body known as Flavin adenine dinucleotide. So we have Fad that picks up two of these h ions that each contain one electron each. And so we form when this happens, we form Nfadh two because each of these HS contains an electrons and that gives a total of two electrons. And so three of these are nadhs and one of them is fadh too, as we'll see in this discussion here. Now, this is what we form when a single pyruvate is broken down.
