| Illustration of a root nodule on grass containing Rhizobia bacteria, highlighting the biochemical process of nitrogen fixation. The enlarged section shows Rhizobia converting atmospheric nitrogen (N?) into ammonia (NH?) using the nitrogenase enzyme, which requires molybdenum as a cofactor. Molecular structures and arrows indicate the conversion process. The soil cross-section reveals root structure, with labeled components indicating locations of the nodule, Rhizobia, and molybdenum. This diagram emphasizes the symbiotic relationship between grass and bacteria, essential for nitrogen assimilation. |
