TL;DR: By reducing nitrite to NO, plant mitochondria preserve the capacity to oxidize external NADH and NADPH and retain a limited power for ATP synthesis complementing glycolytic ATP production.

TL;DR: The kinetics of hemoglobin oxidation and NO generation at a range of oxygen partial pressures are characterized and it is found that the deoxy-re reaction runs in parallel with and partially inhibits the oxy-reaction.

TL;DR: In this paper, the authors investigated operating variables of the electrochemical method including the current input, pH, conductivity, buffer solution and initial nitrite and ammonia concentrations were considered to determine their respective effect on the efficiency of the removal of Nitrite and Ammonia.

TL;DR: The very low steady-state [NOaq] observed during denitrification imply that the maximum activity of nitric oxide reductase in vivo, if it could be realized, would be large relative to that for nitrite reduct enzyme in vivo.

TL;DR: Electrochemical results and DFT calculations indicate that both nitrate and nitrite are twofold coordinated to the Cu(100) surface.
Abstract: Nitrate adsorption and reduction on Cu(100) in acidic solution is studied by electrochemical methods, in situ electrochemical scanning tunneling microscopy (EC-STM), surface enhanced Raman spectroscopy (SERS), and density functional theory (DFT) calculations. Electrochemical results show that reduction of nitrate starts at -0.3 V vs Ag/AgCl and reaches maximum value at -0.58 V. Over the entire potential region interrogated adlayers composed of nitrate, nitrite, or other intermediates are observed by using in situ STM. From the open-circuit potential (OCP) to -0.22 V vs Ag|AgCl, the nitrate ion is dominant and forms a (2 x 2) adlattice on the Cu(100) surface while nitrate forms a dominantly c(2 x 2) structure from -0.25 to -0.36 V. The interconversion between the nitrate and nitrite adlattices is observed. DFT calculations indicate that both nitrate and nitrite are twofold coordinated to the Cu(100) surface.
