Question

Nitrogenase enzyme is
A. Magnesium iron protein
B. Molybdenum-iron protein
C. Iron copper protein
D. Nickel- iron protein

Answer 1

Hint: The catalyst is liable for nitrogen fixation the nitrogenase shows a serious extent of preservation of the structure, capacity, and amino corrosive arrangement across wide phylogenetic ranges. This section alludes to the nitrogenase iron-molybdenum cofactor biosynthesis protein NifN, which shapes an [alpha]2 [beta]2 tetramer with NifE.

Complete answer:
These enzymes are answerable for the decrease of nitrogen to alkali. Nitrogenases are the main group of compounds known to catalyze this response, which is a key advance during the nitrogen fixation.
Nitrogen fixation is required for all types of life, with nitrogen being fundamental for the biosynthesis of atoms (nucleotides, amino acids) that make plants, creatures, and different life forms. They are encoded by the Nif genes or homologs. They are identified with protochlorophyllide reductase.
The molybdenum-iron protein is important for the nitrogenase complex that catalyzes the key enzymatic responses in nitrogen fixation. Nitrogenases are proteins that are delivered by specific microscopic organisms, for example, cyanobacteria (blue-green growth).
Organic nitrogen fixation is cultivated through the reactant activity of a complex chemical framework known as nitrogenase and it is the main known group of proteins that achieves this cycle.
The quality of the Nitrogen atom is a result of its N-N triple bond. To break nitrogen molecules requires breaking of every one of the three substance bonds.
So Nitrogen obsession utilizing nitrogenase requires rather enormous contributions of energy to drive the cycle. Nitrogenase comprises two significant protein segments, to be specific, dinitrogenase (MoFe-protein) and dinitrogenase reductase (Fe-protein).

So, the correct answer is “option B”.

Note:
The enzyme, a substance that goes about as an impetus in living life forms, managing the rate at which synthetic reactions continue without itself being modified in the process. The natural cycles that happen inside all organisms are chemical reactions, and most are directed by chemicals. Without compounds, huge numbers of these responses would not occur at a distinguishable rate. Catalysts catalyze all parts of cell digestion.
