Nitrogen cycle

Global Nitrogen Cycle: Critical Enzymes, Organisms, and Processes nitrogen cycle

Free-living nitrogen-fixing bacteria are abundant in the soil and convert gaseous nitrogen into ammonium by reducing it This reduction is endothermic,

krebs cycle Certain types of bacteria are able to use the free nitrogen in the air to make nitrogen compounds through a process called nitrogen fixation  Nitrogen cycle Organic nitrogen compounds Nitrogen-containing compounds are important in plants Examples are proteins , nucleotides Nitrogen Cycle
