So once the binding takes place in the second half cycle, the two protons are essentially transported into the intermembrane fluid of the mitochondria and the two electrons follow this same pathway. So this electron follows this pathway, binds into the Hein group, not the heme group, the two fe two sulfur group. And then the electron moves on and binds until the heme group of Cytochrome C before actually being picked up by a second different cytochrome C molecule. So this cytochrome C molecule is different than this cytochrome C molecule. So this one basically detaches and an oxidized version. Another one basically reattaches.
