What is the chemical reaction catalyzed by nitrate reductase?
Nitrate reductase catalyzes the reduction of nitrate (NO3-) to nitrite (NO2-). This reaction involves the transfer of electrons to convert nitrate into nitrite, an important step in the nitrogen cycle.
Which of the not a prosthetic group of nitrate reductase?
Nitrate reductase does not contain the prosthetic group heme. Instead, it typically contains molybdenum cofactor (Moco) and heme iron-sulfur center as prosthetic groups.
What happens to nitrate when you electroplate sliver nitrate?
When silver nitrate is electroplated, the silver ions in the silver nitrate solution are reduced at the cathode, forming a silver metal coating on the substrate. The nitrate ions from the silver nitrate solution are left in the solution without participating directly in the electroplating process.
Why is silver nitrate not used in electroplating silver?
Silver nitrate is a compound used for making silver salts, not for electroplating silver. In electroplating, a pure silver metal source is needed as the source of silver ions, not silver nitrate. This is because the ions in silver nitrate are not stable in solution for electroplating.
What is it called when and enzyme and substrate come together?
When an enzyme and substrate come together, it is called the enzyme-substrate complex. This complex is a temporary intermediate state in which the enzyme binds to the substrate to catalyze a chemical reaction.
Protocol for nitrate reductase using sodium nitrite as standard?
To measure nitrate reductase activity using sodium nitrite as the standard, you would need to create a standard curve by plotting the absorbance values of known concentrations of nitrite against their concentrations. Then, you can measure the nitrate reductase activity by monitoring the decrease in nitrite concentration over time in the presence of the enzyme. The activity can be calculated based on the slope of the standard curve and the decrease in nitrite concentration in the enzyme reaction.

If you have isolated a bacterium that grows in a medium containing an organic substrate and nitrate in the absence of oxygen The nitrate is reduced to nitrogen gas This bacterium is?
This bacterium is likely a denitrifying bacterium. Denitrifying bacteria are able to use nitrate as a terminal electron acceptor in the absence of oxygen, converting it to nitrogen gas through denitrification.

primarily the liver
Can HMG-CoA reductase inhibitors be taken by breastfeeding women?
HMG-CoA reductase inhibitors (such as lovastatin, pravastatin, fluvastatin and simvastatin) should not be used by women who are breastfeeding their babies.
Griess manual METHOD for nitric oxide?
The Griess assay is a simple colorimetric method used to quantify the levels of nitric oxide (NO) in a sample. In this method, nitrate and nitrite are first converted to nitrite by a nitrate reductase enzyme. The nitrite is then reacted with a Griess reagent to form a purple compound whose absorbance is measured at 540 nm. This absorbance is directly proportional to the concentration of NO in the sample.
