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 ...

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration -- using oxygen to generate cellular energy -- differently from other organisms such as ...

Researchers in Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ...

Yeast was used because it is a unicellular organism in the Fungi Kingdom The Next Generation Science Standards (NGSS) emphasize teaching cellular respiration as part of a unit on ecosystems If you’ve ...

Researchers on Monday said they found the first animal out of millions of known species that can survive its entire life without oxygen. The Henneguya salminicola (H. salminicola) normally lives in ...

Researchers have discovered the only known animal that does not need oxygen to survive, a common parasite that largely preys on salmon. The study, published Tuesday in the journal Proceedings of the ...

As bacteria adapt to hotter temperatures, they speed up their respiration rate and release more carbon, potentially accelerating climate change. By releasing more carbon as global temperatures rise, ...

The single-celled ciliated organism Tetrahymena uses a different set of proteins for respiration from plants, animals or yeast, a new study shows. The findings reveal unsuspected diversity in how ...

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 ...

Researchers on Monday said they found the first animal out of millions of known species that can survive its entire life without oxygen. The Henneguya salminicola (H. salminicola) normally lives in ...
