Cell and Mitochondria Respiration of Naegleria fowleri
The Journal of Parasitology, 1979Whole 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.

Effect of biguanides on the respiration of tumour cells
Experientia, 1968E stato studiato l'effetto di un gruppo di derivati biguanidici sulla respirazione in vitro di cellule tumorali ed epatiche. I composti esaminati sono tutti capaci di inibire, in vario grado, lo sviluppo del tumore ascite di Ehrlich del topo, tranne uno, privo di attivita antitumorale in vivo.

Tumor Cell Respiration Following Irradiation
Radiology, 1978Oxygen consumption rates for mouse mastocytoma cells examined from 3 to 4 hours after x-irradiation with 250-2000 rads were consistently higher than controls. Cyclic fluctuations in oxygen consumption per cell were dose-dependent; peaks in consumption were generally greater in magnitude and occurred later in time with increasing dose.

An electrochemical method for determination of cell respiration
Journal of Basic Microbiology, 1985AbstractThe respiration of microorganisms was determined with a sensor composed of microorganisms and an oxygen electrode. The microorganisms (suspensions of about 100 μl) are sedimented by centrifugation in a special tube on a very thin paper layer (diameter 4 mm). This paper layer is sandwiched between a polyethylene membrane and a dialysis membrane.

Kinetic trapping of oxygen in cell respiration
Nature, 1996Cell 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.

Respiration in the Living Cell
The Quarterly Review of Biology, 1941The 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 ...

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.

The complexities of respiration in photosynthetic cells
Trends in Biochemical Sciences, 1983(3). The loosely held view that mitochondrial respiration is restricted by a high cytosolic ATP/ADP ratio in the light has been challenged by two recent reports. At the University of Adelaide, Dry and Wiskich 3 studied the respiration of pea leaf mitochondria in the presence of a creatine/ creatine kinase system and varying levels of ATP, and observed ...

Mitochondrial respiration of the photosynthesizing cell
Russian Journal of Plant Physiology, 2016Current notions on respiration of photosynthesizing cells are reviewed. Over the past three decades, the modern methods based on isotope techniques and reverse and molecular genetics provided convincing evidence that mitochondrial respiration is functional in the light and contributes to the creation of optimal conditions for photosynthesis and for ...
