Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: N2 + 16ATP + 8e- + 8H+ -> 2NH3 + H2 + 16ADP + 16PiMaitiro acho akabatanidzwa nehydrolysis ye16 yakaenzana neATP uye inofambidzana nekubatanidzwa kweimwe yakaenzana neH2. Kushandurwa kweN2 kuva ammonia kunoitika muchikwata chesimbi chinonzi FeMoco, kupfupikiswa kweshoko rokuti iron-molybdenum cofactor. Nzira yacho inopfuurira kupfurikidza nhevedzano yematanho eprotonation uye kuderedza umo nzvimbo inoshanda yeFeMoco inonyorovesa N2 substrate. Muzvikafu zvinorarama zvakasununguka, ammonia inogadzirwa ne nitrogenase inosanganiswa ne glutamate kuburikidza ne glutamine synthetase / glutamate synthase nzira. Majini eNif ehutachiona anodiwa pakugadziriswa kwenitrogen akapararira munzvimbo dzakasiyana-siyana. Nitrogenases inokurumidza kuparadzwa neoksijeni. Nokuda kwechikonzero ichi, mabhakitiriya akawanda anorega kugadzira enzyme yacho kana paine okisijeni. Zvinhu zvipenyu zvakawanda zvinobatanidza nitrogen zvinongovapo mumamiriro ezvinhu asina mhepo, zvichifema kuti zvideredze mwero weoxygen, kana kuti zvinosunga okisijeni neprotein yakadai selehemoglobin.  Mubvunzo: Zvinhu zvipenyu zvakawanda zvinobata nitrogen zviri kupi?
