Now, once we form the fadh two, the fadh two remains bound to complex two. And in complex two, the two electrons are abstracted from fadh two, and they move on to series of iron sulfur clusters, iron sulfur groups. And ultimately, those two electrons end up being bound to Ubiquinone, coenzyme Q, the same coenzyme Q that we discussed in this particular case. And again, the coenzyme Q, once it binds those two electrons, it abstracts two H plus ions to form Ubiquinol. The ubiquinol then departs. It detaches from the complex and moves on to complex three.
