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 ...

It has fewer than 10 cells, lives within the muscles of salmon and doesn't have mitochondria. It sounds like science fiction, but researchers say they've recently discovered the first-ever "animal" ...

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 ...

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 ...

Cells require energy for activities such as growth and cell division. In animals, muscle cells require energy for contracting and nerve cells require energy for transmitting nerve impulses. The energy ...

Respiration is the physiological process through which oxygen in the environment can be exchanged with carbon dioxide from an organism. This process requires specialized organs such as the lungs or ...

Vol. 95, No. 1, White on Green: Under-Snow Microbial Processes and Trace Gas Fluxes through Snow, Niwot Ridge, Colorado Front Range (Aug., 2009), pp. 13-21 (9 pages) Numerous studies have demonstrated ...

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 ...
