Mitochondrial Chitter-Chatter: Unveiling the Molecular Structures of Cellular Respiration

In a Molecular Cell study, Assistant Professor James Letts and colleagues revealed that the function between the complexes in the respiratory supercomplex is more nuanced and variable than previously hypothesized. David Slipher/UC Davis

In order to generate energy, our bodies transfer electrons from food—sugars, fats and proteins—to molecular oxygen, which allows our cells to respire and function. Performed by the mitochondrial electron transport chain (ETC), this process creates energy-storing and -transporting adenosine triphosphate (ATP), the “molecular currency” for energy in the cell.
