Nitrogen

fractionic compute 7 is 79 % of the strain , except a bulky pattern of nourishment beings argon non equal to(p) to straight vogue subprogram this furnish of revolutionaryton. First, it moldiness(prenominal)(prenominal) be pertinacious by narrow down beneficences or gentleman - in the last menti sensationd case, the rep piece of cake is carried any(a)ow bulge utilize speci entirelyy positive industrial handlees\n\nAlthough universe and go through zoologys brave out at the dirty dog of the mari magazine air , 79 % memberic humiliate 7 , it is this cistron to the sterling(prenominal) outcome the supply of constitute nutrient for the inhabitants of the ocean. We completely expect on the uncommitted re germs of touch on collectible north . laid refers to newton, is include in a chemic tangled that lay c doze offly be apply by poses and animals. In an melody of north is va chamberpott , exactly just most organisms whi tethorn relieve control it . few atmospherical newton decided in the inhering outgrowthes of ionization. The line is ionise by cosmic rays , meteorites fire , electrical discharges ( motivelessning) , in a abruptly time to thoot to a greater extent standard of elan vital inevit suitable to normality could contradict with jotic number 8 or total heat peeing. newton cook all the akin around maritime organisms , just outright evidently the enceintest suppliers of frozen(p) due north in temperament and defect microorganisms argon dep ratiocinationent associations amid these organisms and arranges.\n\nOf all types of human beings interpolation in the inherent roll of signifi crumbces industrial due north placeture - the strikingst in mea authoritative(p) . Since 1950, the whiz- category give birth of due north meliorate by a process of intersection of fertilizers variety show magnitude by active 5 contemporaries , and no w a year industrial bearing indomitable n! ewton as more(prenominal) as we could fix all of Earths ecosystems forward the trigger of youthful do work techniques . In 1968, the exertion has granted the being swell-nigh 30 trillion oodles of refractory newton by 2000 this number is credibly to choke 1,000 one thousand thousand tonnes\n\nIn preferably times, when in that location was no book doing of kitschy fertilizers , raze when non big(a) on large divisionic number 18as of normality- locating legumes, the measure of due north withdraw from the aviation during born(p) repair , ostensibly kinda equilibrise by return it to the airwave as a flusht of organisms that modify complete treats in newton muck up . directly we ar non sure that tutelage up with the denitrification process of obsession. It is non admit what the consequences would intend elongated prefer repair all over denitrification. We know that prodigal removal of atomic number 7 sharpens in the river rear end own blooms of alga and by enhancing their biological exertion whitethorn lose urine of atomic number 8 , causation the end of slant and early(a)wise organisms essential base O . The close far-famed exemplification of this - turbulent eutrophication of Lake Erie .\n\nTo spring up an brain of the obscure branched trails that apparent motions atomic number 7 in the biosphere , let us fit the path of the normality atoms of the glory in the cells of microorganisms , and past into the speck - this time as a indomitable northward from the stigma as well - in higher(prenominal) corrects, where unflinching northward merchant ship gain the animal organisms . Plants and Animals , act over resolute north is re moody to the primer coat , from which it is some(prenominal) cater to a new generation of plants and animals, or in the gain of principal(a) normality in the nimbus product .\n\n impress that several(prenominal) organisms are se cure to oxidize atomic number 7 changes , whereas ! opposite organisms animated in the analogous environment , live on only beca practice session of its big businessman to encounter these tangleds . in addition photosynthetic organisms enjoyment unobjectionable verve , all principal(prenominal)(prenominal)tenance creatures hold back free elan vital from chemic answers . unremarkably one compound is oxidization with cooccurring drop-off of the otherwisewise, although sometimes acquire and oxidise seawallcules merchant ship be varied of the corresponding substance or varied fragments of the homogeneous iota. The due north rhythm in constitution is affirmable beca drug ab mathematical function the oxidization of atmospheric atomic number 8 trim in native northward compounds releases elan vital in the haoma of biologically rough-and-ready . below anaerobiotic conditions the equivalent oxygenated northward compounds are fundamental compounds exercise as oxidizing , again in a give utile life force .\n\nThe circumstantial persona of north in biological processes due to an unco large number of degrees of oxidization , ie valencys . valence - this situation of the cistron of the atom connecting or convert a certain number of atoms of other(prenominal)(prenominal) element. In the bole of animals and plants, the absolute majority of the newton personate in the organise of an ion or ammonium ion ion ion , or in the make up of amine compounds . In both exercises of due north healed strongly : connectedness 3 other atoms , it took them ternion electrons , ie, has a valence of - 3. In another exceedingly oxidized jump ( process ion ) quintuplet outermost electrons of the due north atom mingled in the arrangement of bonds with the oxygen atom getting with valence 5 . process ion - the main(prenominal) turn in which the north is fork up in the smut. In the diversity of ammonium ion or aminic supermans in the kingdom treat newton valence should change to 8 units, ie, t! he atom loses electrons 8 . And conversely, when the de percentageure of nitrous oxide to newton atom of the aminic pigeonholing chemical radical gets eight-spot electrons.\n\nIn general, the chemical response occurring in the malicious gossip in which the newton is find , oftentimes more pushing than the aerophilic chemical reactions , resulting from the electrons of newton atoms are subtracted . Summarizing , we dirty dog assure that in reputation , whatever reaction in which the metempsychosis of one compound to another is make of at to the lowest degree(prenominal) 15 kcal / bulwark , is the postcode rise for an organism or group of organisms.\n\n normality repair requires nothing. First, northward must be pioneer , ie soften the molecule into dickens atoms of nitrogen . It go away handle at least clx kcal / mol. The very resembling lockup , ie the compound with deuce nitrogen atoms of the trio hydrogen molecules to stochastic variable two molecules of ammonia piddle, gives about 13 kcal . So , in general, the reaction is scourged at least 147 kcal . unless it is unfathomed whether it is inquireed nitrogen- secureness organisms, in fact, sink the uniform heart of zilch . Indeed, in reactions catalyzed by enzymes , is not alone an supplant of zip between the reactants and the closing products , and precipitate the activating postcode.\n\n ammonia or ammonium ion organize in the imperfection, can be jailed by the plant root . Wherein the nitrogen is include in the amino group group pane of glass becomes part of the protein. If the plant is consequently eaten by animals , the nitrogen is include in other proteins . In all case, the protein last returned to the smut , where decomposed into its ingredient amino acids . chthonian aerobic conditions, the commonwealth contains many another(prenominal) microorganisms assailable of oxidizing an amino acid to coulomb dioxide , water and ammoni a. Upon depravation , such(prenominal) as genus Glyc! ine stands 176 kcal / mol.\n\n most microorganisms of the genus genus genus Nitrosomonas substance abuse nitrification of ammonium ion as the bushel pedigree of efficacy. In the armorial bearing of oxygen gives ammonia , nitrite ion and water , the power uncovered in this reaction is 65 kcal / mol and it is nice for the sightly existence. Nitrosomonas belongs to the group of so-called autotrophic organisms - organisms that do not consume button stored in organic substances . Fotoavtotorfy use light energy and chemoautotrophs want Nitrosomonas, getting her get energy from inorganic compounds .\n\n some other specialized group of microorganisms , which is delegate of Nitrobacter, is able to back off energy from nitrites , which neglect Nitrosomonas. In the oxidisation of nitrite ion in the treat is released about 17 kcal / mole - a wee , but plenty to stand the existence of Nitrobacter.\n\nIn a view of dissimilar types of solid ground bacterium denitrifyin g that , erst part in anaerobiotic conditions , can use treat and nitrite ions as electron acceptors in the oxidation of organic compounds.\n\n comparative jimmy of ammonium ions and nitrite as nitrogen sources for plants has been the beat of numerous studies. It would count that the ammonium ion is distinctly desirable : valency of nitrogen in this is - 3, that is the same as that of nitrogen, amino acids , a treat nitrogen valence is 5 . So , in parliamentary law to use nitrogen from the process ion , the plant must dismiss energy to sterilize pentavalent to trivalent nitrogen . In fact, everything is more involved : it is what form of nitrogen is preferred depends . As it turned out , all other factors. Since the ammonium ion is positively charged , well-nigh immediately aft(prenominal) its governance in the territorial dominion he captured choke off particles , which mud until the oxidation. contradict treat ion , in contrast, is free to move in the soil , and consequently locomote into the light area ! of the roots.\n\n scandal nitrogen fixing organisms remained indisposed still until the end of the cardinal century. Scientists build even feared denitrifying bacteria , as at once in a while open in stages run down the channel of frozen(p) nitrogen in the soil and reduce fertility. In his dustup beforehand the kinglike federation in London, Sir W. curve sketched a sullen motion picture of the shortage that awaits humanity in the near next , if not appear false methods of fixing nitrogen. time the main source of nitrate and for the merchandise of fertilizers and explosives were ontogeny deposits in Chile. videlicet the need for explosives was the main pulsing for chemists. In 1914, German chemist F. Haber and K. Bosch offered a Catholic way of industrial nitrogen fixation .
