Researchers have found what is perhaps the oldest enzyme in cellular respiration. They have been able to isolate the extremely fragile 'Rnf' protein complex from the heat-loving bacterium Thermotoga ...

Oxygen-consuming organisms obtain energy through cellular respiration, which is the transformation of carbohydrates and oxygen into carbon dioxide and water. This process also produces toxic oxygen ...

Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of ...

IN “his Croonian Lecture on the “Mechanisms of Cellular Respiration” delivered to the Royal Society on December 13, Prof. D. Keilin, Quick professor of biology and director of the Molteno Institute in ...

A study investigating how a cellular enzyme affects blood glucose levels in mice provides clues to pathways that may be involved in processes including the regulation of longevity and the ...

In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances by means of ...
