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. And so we see that in a single queue cycle, we actually generate two reduced cytochrome C molecules because of the fact that a single Ubiquinol can carry two electrons, but a single cytochrome C can only bind and carry a single electron. Now the other electron basically moves, attaches onto the heme groups of cytochrome B, and then that electron is picked up by the semiquinone radical ion and now gains two electrons. And then it takes two protons from the matrix of the mitochondria.
