Respiration in cell development
Archiv f�r Mikrobiologie, 1971Dark oxygen uptake was measured manometrically for cells of green high-temperature alga, Chlorella 7-11-05, separated from nonsynchronized populations by centrifugation into fractions of predominantly small or large cells. In the presence of exogenous glucose, respiration activity of the smaller (younger) cell fraction was invariably higher than that ...

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.

Correlation Between Respirator Fit and Respirator Fit Test Panel Cells by Respirator Size
Journal of Occupational and Environmental Hygiene, 2008The National Institute for Occupational Safety and Health (NIOSH), recognizing the difficulties inherent in using old military data to define modern industrial respirator fit test panels, recently completed a study to develop an anthropometric database of the measurements of heads and faces of civilian respirator users.

Immobilised plant cells: Respiration and oxygen transfer
Journal of Chemical Technology and Biotechnology. Biotechnology, 1985AbstractThe influence of support material (calcium alginate, x‐carrageenan and agarose), cell loading and, in case of alginate, bead diameter on the rate of respiration of immobilised plant cells (Daucus carota) was investigated. No significant differences were observed between the three supports and no loss of respiration activity occurred as result ...

ACINAR CELL RESPIRATION IN EXPERIMENTAL ACUTE PANCREATITIS
SHOCK, 1995The early pathogenetic steps that finally lead to acinar cell necrosis in acute pancreatitis have been characterized only scarcely as yet. Among a lot of hypotheses, one concept favors disturbances of cellular energy metabolism as a major factor that contributes to preterm cell decline.

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.

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, 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.
