What do nitrogen fixing bacteria use to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen?
Nitrogenase enzyme is used by nitrogen fixing bacteria to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen.Nitrogenase is the enzyme used by some organisms to fix atmospheric nitrogen gas (N2). It is the only known family of enzymes which accomplishes this process
Do rhizobium in root nodules of leguminous plants convert nitrogen gas to amino acids?
Yes, it does. First, nitrogen gas is converted to ammonium compounds by rhizobium. This is usually done: 1. In anaerobic conditions(which the plant cells provide for them) 2. In the presence of the enzyme nitrogenase 3. In the presence of H+ions. Then, the ammonium compounds are converted into amino acids which are exported to plant cells to make protein.
The nitrogen fixing Nitrogenase complex is oxygen-lible?
Nitrogenase is unable to discriminate between O2 and N2, and the O2 will degradatively oxidize the FE-S cofactors of the nitrogenase, rendering it more inefficient under increasingly aerobic conditions.
What is the key enzyme in nitrogen fixation?
nitrogenase
What is element an essential component of the enzyme nitrogenase that converts nitrogen into ammonia?
Nitrogenase contains an FE-S cluster at the active site, and most contain a molybdenum atom centered in the heterometal complex.
How do azotobacter make anaerobic environment for nitrogenase enzyme?
by concentrate oxygen using leghemoglobin

How anabaena solve the problem of nitrogenase not to react with oxygen?
They differentiate a select few cells into specialized semi-anaerobic nitrogen fixing cells called heterocysts.
Which event breaks down the nitrogen in the atmosphere and converts it to a form that can be used by plants and animals?
Nitrogen fixation is how atmospheric nitrogen is processed. This occurs during lightning strikes but mainly is processed by diazotrophs, or free living bacteria with nitrogenase.

Process of converting nitrogen gas into ammonia?
Is known as nitrogen fixation, done with the enzyme nitrogenase found in nitrogen fixing bacteria.
How do colonies of cyanobacteria benefit aquatic organisms?
Colonies of cyanobacteria benefit aquatic organisms because they can be an important source of food to organisms.Daily random word from ClarrissaBlooms : Smile
How does nitrogen reacts with fire?
ReactionsNitrogen is generally unreactive at standard temperature and pressure. N2 reacts spontaneously with few reagents, being resilient to acids and bases as well as oxidants and most reductants. When nitrogen reacts spontaneously with a reagent, the net transformation is often called nitrogen fixation.Nitrogen reacts with elemental lithium at Lithium burns in an atmosphere of N2 to give lithium nitrid: 6 Li + N2 → 2 Li3NMagnesium also burns in nitrogen, forming magniesium nitride. 3 Mg + N2 → Mg3N2N2 forms a variety of oadducts with transition metals. The first example of a dintrogen complex is Ru(NH3)5(N2)2. Such compounds are now numerous, other examples include IrCl(N2)(PPh3)2, W(N2)2(Ph2CH2CH2PPh2)2, and [(η5-C5Me4H)2Zr]2(μ2,η²,η²-N2). These complexes illustrate how N2 might bind to the metal in nitrogenase and the catalyst for the Haber process. A catalytic process to reduce N2 to ammonia with the use of a molybdenum complex in the presence of a proton source was published in 2005.The starting point for industrial production of nitrogen compounds is the Haber process, in which nitrogen is fixed by reacting N2 and H2 over an iron(III) oxide (Fe3O4) catalyst at about 500 °C and 200 atmospheres pressure. Biological nitrogen fixation in free-living cyanobacteria and in the root nodules of plants also produces ammonia from molecular nitrogen. The reaction, which is the source of the bulk of nitrogen in the biosphere, is catalysed by the nitrogenase enzyme complex which contains Fe and Mo atoms, using energy derived from hydrolysis of adenosine triphosphate (ATP) into adenosine diphosphate and inorganic phosphate (−20.5 kJ/mol).Hope it helped Bruce
How do plants take nitrogen from the atmosphere?
Plants absorb nitrate compounds from soil through their root hairs, which are outgrowths of the trichoblast cells in the roots.Most plants are not able to use nitrogen as such (N2), though some, including legumes and casuarinas, supply water and food to symbiotic nitrogen-fixing bacteria in specialised root nodules, and these fix nitrogen to nitrate which they supply to the plants.
