Summary Introduction

To write:

The chemical reaction catalyzed by nitrate reductase

Introduction:

Catalysis is the process that raises the rate of a chemical reaction by adding an element known as a catalyst. Catalyst is not utilized in the reaction. The catalyst usually forms a temporary intermediate product.

Chemical reactions occur rapidly in the presence (or existence) of a catalyst because the catalyst gives an alternative reaction pathway with lower activation energy than the non-catalyzed mechanism.

In the presence (or existence) of a catalyst, less free energy is needed to reach the transition state, but the total free energy to the products from the reactants does not change. As compared to the non-catalyzed reaction, catalyzed reactions have lower activation energy.

Explanation of Solution

Nitrate reductase is molybdenoenzymes. It is responsible for catalyzing the nitrate assimilation (rate-limiting step). It is not only accountable for catalyzing, but also increases the production of amino acids in tea leaves.

Nitrogen assimilation forms organic nitrogen compounds (like amino acids) from inorganic nitrogen compounds existing in the atmosphere. The first step of this process is the decrease of nitrate to nitrite in the cytosol. It is catalyzed by nitrate reductase.

  NO3+NAD(P)H+H++2eNO2+NAD(P)++H2O

Conclusion

The chemical reaction catalyzed by nitrate reductase is nitrogen assimilation.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.
