Most modern organisms rely on oxygen to metabolize food and release energy. Oxygen serves as the final electron acceptor in a chain of reactions that produces energy. But bacteria, far older than ...

That reaction is anaerobic respiration, which produces sulfur species,” says Fakhraee. The sulfur species formed by the reaction is iron sulfide or pyrite, which is also known as “fool’s ...

Electric respiration explained Most modern organisms rely on oxygen to metabolize food and release energy. Oxygen serves as the final electron acceptor in a chain of reactions that produces energy.

Nitrate is used by S. Typhimurium as an electron acceptor for anaerobic respiration (40). By powering nitrate respiration, intestinal inflammation fuels growth of S. Typhimurium to increase the ...

These elements have only three electrons in their valence shell, so where N-type semiconductors are doped with electron donors, P-type semiconductors use dopants that act as electron acceptors.

The researchers confirmed by additional experiments that both enzymes used F 420 as an electron acceptor. "This discovery breaks a dogma in the scientific field of anaerobic metabolism, as it ...

To get into specifics, the small intestine – a part of the gut – is mostly composed of facultatively anaerobic bacteria. By providing oxygen as an electron acceptor into the gut through human ...
