The anammox reaction consists of __________ and, as a consequence, __________.
A) reduction of sulfate by ammonia; sulfur and nitrogen are incorporated into amino acids
B) reduction of ammonium to form nitrite; plants can absorb nitrite
C) anaerobic ammonium oxidation by nitrite; large amounts of N₂ are released into the atmosphere
D) reduction of ammonium by water; ammonium becomes ammonia
E) reduction of N₂ to ammonium; nitrogen atoms are incorporated into amino acids

Question

Quizplus · Accepted Answer

The anammox reaction involves anaerobic oxidation of ammonium (NH₄⁺) with nitrite (NO₂⁻) to generate molecular nitrogen (N₂) and water (H₂O). The reaction does not involve sulfate, sulfur, nitrite, or ammonia reduction, nor does it result in incorporation of nitrogen into amino acids. Choice C is the only option that accurately describes the anammox reaction.

The Anammox Reaction Consists of __________ And, as a Consequence
