Nitrogen-fixing bacteria are the microbial organisms that play an important role in the conversion of atmospheric nitrogen gas into reactive nitrogen such as ammonia, nitrogen oxide, and nitrous oxide. These types of bacterias are comprised of an enzyme known as the 'nitrogenase enzyme' that allows the nitrogen gas to mix with hydrogen and eventually produces ammonia.
This ammonia is then concentrated in the soil and is later taken up by the plants which are highly essential for them as they ammonia are their main source of nitrogen. This helps in the growth, development, and expansion of the overall plant body.
Akira turns in a written lab report to his science teacher. ... Akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowered the activation energy needed to start the reaction.
