This mechanism links the gradual oxidation of electron donors in the electron transport chain to the pumping of protons through the membrane, generating the electrochemical gradient required for ...

Many cells can use oxygen or nutrients to generate fuel, and the process is similar in many organisms that use an electron transport chain. But scientists have found that in a tiny organism, things ...

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 ...

Researchers advocate ‘rewriting’ of textbooks on electron transport chain in mitochondria A paper by scientists affiliated with the University of São Paulo highlights new discoveries ...

A new study suggests electron transport chains—a metabolism system that creates usable energy—may have been present in Earth’s prebiotic minerals and sea water.
