Subject: How does Coenzyme Q pump protons across the mitochrondria membrane?

Hi, I'm a junior at Alhambra High School. My biology class recently 
learned about cellular respiration. We learned that protons are captured 
by carriers such as Coenzyme Q and pumped into the outer mitochondria 
compartment. My textbook saids that the protons captured by the carriers 
when they are reduced, but it doesn't expalin how it happens. Do the 
protons just enter the carriers and attract to the electrons? Are there 
channels which the protons go through to enter the carriers? Thanks for 
your time!
