full_question: This compound and water are produced in a process found in Brocadia and other bacteria with distinctive ladderane lipids. This gas is produced in a specialized organelle with a riboplasm and paryphoplasm, which is known as the anammoxosome. Oxygen often interferes with the reduction of this element, which can be alleviated by leghemoglobin. An enzyme that reduces this compound relies on an iron molybdenum cofactor found in the legume-associating Rhizobium bacteria. Diazotrophs can aid "fixation" of this compound and convert it to ammonia. This element, phosphorus, and potassium are the major ingredients of fertilizers. For 10 points, name this gas, central to a biogeochemical cycle, which makes up the majority of the atmosphere.
