1. The Mitochondrial Respiratory Chain

Electrons Are Funneled to Universal Electron Acceptors

Electrons Pass through a Series of Membrane-Bound Carriers

Electron Carriers Function in Multienzyme Complexes

Mitochondrial Complexes Associate in Respirasomes

Other Pathways Donate Electrons to the Respiratory Chain via Ubiquinone

The Energy of Electron Transfer Is Efficiently Conserved in a Proton Gradient

Reactive Oxygen Species Are Generated during Oxidative Phosphorylation
