Nitrogen-fixing bacteria in the roots of soybeans help provide a source of nitrogen to the plants,and in exchange,the bacteria obtain food from the plants.Which reaction can these bacteria catalyze?

Question

Quizplus · Accepted Answer

Nitrogen-fixing bacteria in the roots of soybeans convert atmospheric nitrogen gas (N2) to ammonium (NH4+) through the process of nitrogen fixation. This ammonium can then be used by the plant to produce organic molecules such as amino acids and nucleotides. Therefore, the reaction that these bacteria can catalyze is the conversion of nitrogen gas to ammonium (choice C). The other choices involve conversions of nitrogen-containing molecules, which are not part of the nitrogen fixation process.
