From an energy standpoint, uptake and reduction of nitrogen with incorporation into an organic framework is one of the most expensive tasks a tree performs. It would hardly be worthwhile if usable nitrogen in the environment was not at a premium. Trees spends a great deal of energy and carbon chain stock in order to capture and control nitrogen. In this case, to move from soil nitrate to glutamine inside a tree cell requires at least 12 ATPs of energy per nitrogen. To reduce atmospheric dinitrogen gas into glutamine requires at least 16 ATPs of energy per nitrogen plus creation and maintenance of a microbial root nodule.
