The Metabolic Process of Denitrification

Question

The metabolic process of denitrification
A) oxidizes N₂.
B) oxidizes NO₃⁻.
C) reduces N₂.
D) reduces NO₃⁻.

Accepted Answer

The metabolic process of denitrification reduces NO₃⁻ to N₂ or other nitrogen oxides like NO₂, N₂O, or NO, but it does not oxidize them. Therefore, option D is the correct choice as it states denitrification reduces NO₃⁻.
