Now, let's move on, or actually, since we're on the subject, let's look at coenzyme Q. So coenzyme Q, also known as Ubiquinone, is pretty much this small molecule that is dissolved in the membrane of the mitochondria. This is shown here. And because it contains a relatively large hydrophobic region, it can dissolve easily in the membrane. And so it can move across the membrane. And what it does is it takes those electrons from protein complex ones that were received by the NADH molecule, and it shuttles, it moves those electrons onto protein complex three.
