These two bonds are broken. We regenerate these two groups in their original initial oxidized form, and we also form the two water molecules. So this is the final step. Now, by the way, as these electrons are basically moved from the cytochrome seed to these two final groups. And as we ultimately form the two water molecules, a total of four protons for hydrogen ions are essentially pumped from the matrix of the mitochondria to the intermembrane space. And this is shown in the following diagram.
