Food molecules act as electron donors. During each oxidation reaction involved in food breakdown, the product of the reaction has a lower energy content than the donor molecule that preceded it in ...

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 ...

A study conducted by researchers from the University of São Paulo sheds light on new discoveries about the mechanisms of ...

In the bacterium M. smegmatis, an enzyme called MftG allows the cofactor mycofactocin to transfer electrons released during ethanol metabolism to the electron transport chain.

addressed these challenges by creating a programmable quantum system capable of independently controlling the key factors in electron transfer: donor-acceptor energy gaps, electronic and vibronic ...
