New research suggests that certain bacteria began using oxygen nearly one billion years earlier than previously thought. The ...

Bacteria used oxygen far earlier than expected, reshaping views on early life, evolution, and photosynthesis origins.

Scientists at Goethe University uncover how the oldest enzyme in cellular respiration functions – opening the door to potential CO₂ removal from exhaust emissions. Animals, plants, and many other livi ...

Respiration close respirationA chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy. is a chemical ...

A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic ...

The Great Oxidation Event (GOE) some 2.4 billion years ago established the oxygen-rich atmosphere that many living things ...

Microbial fuel cells generate an electric current by harvesting the electrons that are produced by the respiration of substrates. Reporting in Biotechnology & Bioengineering, Kato Marcus and ...

“Microplastics are like rafts — a bacteria on its own might not be able to swim down a river, but riding in its biofilm on a tiny bit of plastic it can be disseminated into many different ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO 2 and water—a process during which the energy-rich molecule ATP is produced.
