Hydrogen metabolism and energy costs of nitrogen fixation
Nitrogen fixation is a highly energy-consuming process, partly because hydrogen is produced during the reduction of dinitrogen to ammonia. As 74 early as 1937 [1], a relationship was found between nitrogen fixation and hydrogen metabolism. Hydrogen production represents a loss of energy and reducing equivalents.
