Measuring mitochondrial respiration in frozen tissue samples provides the first comprehensive atlas of how aging affects mitochondrial function in mice.

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 ...

(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 ...

This test is used to identify microorganisms containing the enzyme cytochrome oxidase (important in the electron transport chain). It is commonly used to distinguish between oxidase negative ...

Dr. Edward Clennan is a professor and the Department head of Chemistry. Nature with photosynthesis elegantly uses supramolecular structures to set up an electron transport chain that spatially ...
