We've discovered that the process occurs in the mitochondrial cristae ... links the gradual oxidation of electron donors in the electron transport chain to the pumping of protons through the ...

(A) Electron micrograph of a human cell section showing three mitochondria. (B) Scheme of the protein complexes that form the ETS, showing the mitochondrial membranes in blue and red; NADH ...

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 ...
