So what this basically does is it accepts our electrons. And when Ubiquinone accepts our electrons, it is reduced. And that reduced version of Ubiquinone is known as Ubiquinol. Now, the most common Ubiquinone molecule in mammals and specifically in humans is coenzyme Q ten. So coenzyme Q ten is basically the specific Ubiquinone that is used by mammals and by humans. Now, once we reduce Ubiquinol to Ubiquinol, ubiquinol then travels from protein complex number one to protein complex number three.
