This mechanism links the gradual oxidation of electron donors in the electron transport chain to the pumping of protons ...

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this ...
