Comparison Between O and OH Intermediates of Cytochrome c Oxidase Studied by FTIR Spectroscopy
Frontiers in Chemistry, 2020 Cytochrome c oxidase is terminal enzyme in the respiratory chain of mitochondria and many aerobic bacteria. It catalyzes reduction of oxygen to water. During its catalysis, CcO proceeds through several quite stable intermediates (R, A, PR/M, O/OH, E/EH).

The Warburg effect suppresses oxidative stress induced apoptosis in a yeast model for cancer. [PDF]
PLoS ONE, 2009 BACKGROUND: Otto Warburg observed that cancer cells are often characterized by intense glycolysis in the presence of oxygen and a concomitant decrease in mitochondrial respiration.

Extensive prokaryotic maintenance respiration in the sea influenced by osmoregulation
Frontiers in Marine Science, 2023 Microbial respiration is the major process consuming oxygen in the biosphere. The relative energy demand from growth of biomass or maintenance activities determines the regulation of respiration with impact on how the development of hypoxia and CO2 ...

Role of Second Quinone Binding Site in Proton Pumping by Respiratory Complex I
Frontiers in Chemistry, 2019 Respiratory complex I performs the reduction of quinone (Q) to quinol (QH2) and pumps protons across the membrane. Structural data on complex I have provided spectacular insights into the electron and proton transfer paths, as well as into the long (~30 ...

Experimental substantiation of permeabilized hepatocytes model for investigation of mitochondria in situ respiration [PDF]
The Ukrainian Biochemical Journal, 2015 To verify experimentally the model of permeabilized hepatocytes, the degree of cell permeability was assessed using trypan blue and polarographycally determined cell respiration rate upon succinate (0.35 mM) and α-ketoglutarate (1 mM) oxidation ...

THE RESPIRATION OF GROWING PLANT CELLS [PDF]
Plant Physiology, 1945 Growing cells of the hypocotyl of Helianthus seedlings were used, employing conditions identical with those of previous experiments cited above. The uppermost thirty-five millimeters of hypocotyl were cut in seven segments of uniform length (5 mm.). The region in which the cells were embryonic was not more than one millimeter long.

RESPIRATION OF RAT PERITONEAL MAST CELLS [PDF]
The Journal of Cell Biology, 1965 Methods for microgasometry of a few hundred mast cells are described. The Cartesian ampulla diver technique is used. The sample size is determined by counting the cells within the diver. The respiration rates at 37°C, expressed in microliters per cell per hour, are 0.29 x 10-6 without substrate and 0.47 x 10-6 with glucose.
