Cell and Mitochondria Respiration of Naegleria fowleri

The Journal of Parasitology, 1979
Whole cell respiration rates were measured polarographically during agitated cultivation of Naegleriafowleri. During log growth, amebae consumed 30 ng atoms O/min/mg cell protein. The ameba's respiration rate gradually decreased 3-fold during stationary phase. Intact mitochondria were isolated from N.

Why mammalian cells respire?

The FASEB Journal, 2017
For decades, the two major functions linked to the mitochondrial respiratory chain has been to replenish NAD or FAD thus allowing the TCA (Krebs) cycle to generate metabolites for the production of macromolecules and to generate a proton motive force for ATP production.

Kinetic trapping of oxygen in cell respiration

Nature, 1996
Cell respiration in eukaryotes is catalysed by mitochondrial enzyme cytochrome c oxidase. In bacteria there are many variants of this enzyme, all of which have a binuclear haem iron-copper centre at which O2 reduction occurs, and a low-spin haem, which serves as the immediate electron donor to this centre.

Absorption spectrum of actively respiring yeast cells

Archives of Biochemistry and Biophysics, 1964
Abstract Spectroscopic observations of intact yeast cells under various physiological conditions revealed that respiring cells have an absorption spectrum which is different from that of resting cells. The most remarkable difference exists in the β-band region of cytochromes; actively respiring cells show a new band at 503 mμ, while resting cells ...

[Respiration in Thiocapsa roseopersicina cells].

Mikrobiologiia, 1976
Oxygen is taken up by the cells of purple sulphur bacterium Thiocapsa roseopersicina BBS grown in the light under anaerobic conditions and in the darkness under aerobic conditions. Respiration is stimulated by sulphide and thiosulphate but not by organic substrates which increase the yield of the cultures. Azide and cyanide inhibit oxygen uptake by the

Respiration in the Living Cell

The Quarterly Review of Biology, 1941
The following review article was sent from the depths of warring China in November, I939. I have undertaken the friendly office of preparing it for publication, but without making any essential alterations or additions. That the literature references, especially those of recent years, are incompletely reviewed, is understandable-our Chinese friends ...

Structural Relations in Cell Respiration

The Quarterly Review of Biology, 1942
T HE living cell exhibits two striking and apparently contradictory properties. In the first place, the substances that make up living protoplasm endow it with a certain morphological stability, which expresses itself grossly in the well-known intracellular structures such as the nucleus, chondriosomes, plastids and so on, and more finely in the ...

Oxygen diffusion and mitochondrial respiration in neuroblastoma cells

American Journal of Physiology-Cell Physiology, 1989
Suspensions of human neuroblastoma cells consume oxygen at a constant rate when the oxygen pressure is greater than approximately 11 Torr. The rate of oxygen consumption, however, becomes dependent on the oxygen pressure below this level. The falling respiratory rate at the lower pressures gives rise to an oxygen pressure for half-maximal respiration (
