Question

diazotrophss enzyme, nitrogenase, catalyzes the addition of hydrogens to nitrogen. what kind of a reaction occurs when the nitrogenase converts n₂ into nh₃? reduction oxidation nitrogen gas (n₂) hydrogen (h)

Explanation:

Reduction is a chemical reaction where a substance gains electrons. In the conversion of nitrogen gas ($N_2$) to ammonia ($NH_3$), hydrogen is added to nitrogen. This addition of hydrogen is a characteristic of a reduction reaction. Oxidation, on the other hand, involves loss of electrons or addition of oxygen. Since hydrogen is being added to nitrogen in this case, it is a reduction process.

Answer:

Reduction
