Often called the "energy currency" of cells, adenosine triphosphate (ATP) is produced in mitochondria by oxidative phosphorylation, a process of energy transfer driven by electron and proton ...

showed that between 30% and 50% of the charge gradient can be attributed to sodium transported in exchange for protons in complex I of the electron transport chain. Complex I transfers electrons ...

but the most crucial is probably the generation of energy as adenosine triphosphate (ATP), by means of the electron-transport chain and the oxidative-phosphorylation system (the “respiratory ...

The reactions of the electron transport chain involve several large membrane protein complexes within the inner mitochondrial membrane. Some are described below. The NADH dehydrogenase complex ...

The study, published in the journal Cell, reveals that respiratory complex I, the first enzyme of the mitochondrial electron transport chain ... complex III or complex IV, confirming that sodium ...

When scientists typically analyze how supercomplexes form, they use antibodies to measure one or two proteins per electron transport chain complex. But as there can be up to 44 proteins in a complex, ...
