Carbon dioxide and the reduction of indophenol and ferricyanide by chloroplasts.
Pea chloroplasts isolated in salt media show decreased rates of 2:6 dichlorophenolindophenol (DCPIP) and ferricyanide reduction when depleted of CO(2) at pH values below 7.5. The greatest effect of CO(2) was on uncoupled systems. The incorporation of 10(-2), 2 x 10(-2) and 4 x 10(-2)m sodium acetate into the reaction mixtures progressively increased the bicarbonate concentration required for ha...
متن کاملNature of oxygen inhibition of nitrogenase from Azotobacter vinelandii.
The reduction of nitrogen, acetylene, azide, and cyanide at various oxygen concentrations by nitrogenase from Azotobacter vinelandii was measured with a well-defined system. Oxygen inhibited the reduction of each substrate uncompetitively. The inhibition constants (K(i)) were 0.014, 0.023, 0.008, and 0.003 atm of oxygen for reduction of nitrogen, acetylene, azide, and cyanide, respectively. The...
متن کاملEnzymic Mechanisms of Pyridine Nucleotide Reduction in Chloroplasts.
The photochemical reduction of triphosphopyridine nucleotide by isolated chloroplasts has been known since 1951 (see “Discussion”). The discovery of this photochemical reaction marked a significant advance in the biochemical analysis of the energy conversion process of photosynthesis because it established the first link between photon capture by chloroplast pigments and the reduction of a phys...
متن کاملAn insight to optical studies of acridine orange cationic dye within nanometer-sized microemulsions at fixed water content
Cationic dye Acridine orange (AO) has wide applications especially in biologicalfields such as analysis of lysosomal and mitochondria content by flow cytometryand so on. In the current work, spectroscopy of acridine orange (AO) dye at bothlow concentrations (mdye/mwater=6.25×10-5, 3.12×10-5) and high concentrations(mdye/mwater=0.002, 0.001) was studied in confined water ...
متن کاملDye Reduction by Illuminated Chloroplast Fragments.
It has been demonstrated that when isolated chloroplasts are illuminated in the presence of aqueous solutions of certain oxidants, oxygen evolution occurs (2, 5, 6, 7, 8, 13). Provided stoichiometric relationships between the reactants and products prevail, the reaction rate can be measured in terms of oxygen production or in terms of changes in the concentration of whatever other molecular or ...
