Question

In Bacteria, the most common oxidized form of nitrogen is ________ and of sulfur is ________.
A) nitrate / sulfate
B) nitrate / sulfite
C) nitrite / sulfate
D) nitrite / sulfite

Accepted Answer

Nitrate (NO3-) is the most common oxidized form of nitrogen in bacteria, while sulfate (SO42-) is the most common oxidized form of sulfur. The other options are not as commonly found in bacteria. Nitrite (NO2-) is a partially oxidized form of nitrogen and is not as stable in the environment as nitrate. Sulfite (SO32-) is a less oxidized form of sulfur and is not as commonly found in bacteria as sulfate.
