Economia Para La Toma De Decisio


economics for decision making | Brambila, Hector Viscencio.Ionic strength dependence of peroxygen/NADH ratio and molecular oxygen production in photosynthetic membranes of Chlamydomonas reinhardtii. Photosynthetic membranes of Chlamydomonas reinhardtii contained approximately 4 mol of NADH per mol of oxidized chlorophyll a, and 4 nmol of O2 per mole of NADH after a steady state was reached. Chlorophyll fluorescence measurements indicated that up to 6 nmol of O2 per mole of NADH was not associated with NADPH production, which suggested that at least part of the NADH was in a form that had not previously been associated with photosynthetic membranes. The photosynthetic membranes contained 15.5 mumol of Mg2+ and 32 mumol of K+ per gram of wet weight. Titration of the Mg2+/K+ ratio in the presence of 140 mM N-methylglucamine hydrochloride indicated that there were approximately 50 nmol of Mg2+ and 80 nmol of K+ per gram of photosynthetic membranes. Peroxide/NADH ratios were measured for NaCl concentrations ranging from 0 to 300 mM. The peroxide/NADH ratios ranged from 0.5 to 2.3, with a peroxide/NADH ratio of approximately 0.7 at 150 mM NaCl and approximately 1.4 at 150 mM KCl. At very low NaCl concentration there was a decrease in the peroxide/NADH ratio. At high NaCl concentrations, the peroxide/NADH ratio increased. The presence of NH4+ at 200 mM NaCl caused a decrease in the peroxide/NADH ratio. Chl a fluorescence measurements indicated that the redox states of Chl a in the photosynthetic membranes were approximately 0.4 and 0.6 during the steady state of growth. The results are discussed in terms of the role of NADH in photosynthetic membranes, the role of peroxide/NADH ratio in determining the physiological state of cells, and the possible role of peroxide/NADH ratio in determining the relative rates of photoinhibition and photolysis.Q: JS Date.toISOString() is not Working Properly Using JS Date object, I'm trying to get the string representation of the time.
