H+/site, charge/site, and ATP/site ratios in mitochondrial electron transport.

H(+)/site, charge/site, and ATP/site ratios have been determined at coupling sites I, II, and III. Three e(-) donors have been used for coupling site III: ferrocyanide, ascorbate + tetramethyl-p-phenylenediamine (TMPD), and succinate + TMPD. The H(+)/site ratios are 4.0 with ferrocyanide and 6.0 with succinate + TMPD (at pH <7.0); the charge/site ratios are 6.0 with ferrocyanide and with succin...

Coupling Geomechanics and Transport in Naturally Fractured Reservoirs

Large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. Canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in Alberta, most of this being bitumen of viscosity greater than 106 cP in the GrosmontFormat...

Damage to mitochondrial electron transport and energy coupling by visible light.

The effect of treating mitochondria with visible light above 400 nm on electron transport and coupled reactions was examined. The temporal sequence of changes was: stimulation of respiration coupled to ATP synthesis, a decline in ATP synthesis, inactivation of respiration, increased ATPase activity and, later, loss of the membrane potential. Loss of respiration was principally due to inactivati...

Electron Transport in III-V Nitride Two-Dimensional Electron Gases

We present a study of electron scattering processes in AlGaN/GaN two-dimensional electron gases. A theoretical study of the effect of deformation potential scattering from strain fields surrounding dislocations is presented. The most important scattering mechanisms limiting electron transport are identified. We find that for AlGaN/GaN 2DEGs, mobility is limited by alloy scattering at high 2DEG ...

Mitochondrial electron transport enzymes in normal and leukemic human leukocytes.

T HE DISCOVERY OF CHANGES in the metabolism of malignant cells, as demonstrated by enzymologic technics, will lead, hopefully, to the better understanding of the nature of the neoplastic process, which is the ultimate necessity for satisfactory therapy. In 1963, Silber, Huennekens, and Gabrio1 reported the presence of increased amounts of two pyridine nucleotide transhydrogenase enzymes in huma...
