Nitrogen Metabolism Flashcards
Why is there a discrepancy between environmental nitrogen and the availability of nitrogen to plants?
What are the major components of the nitrogen cycle?
What are the chemical relationships between molecular nitrogen, ammonium, nitrate, and nitrite?
What is the structure and function of nitrate reductase?
What are the major biochemical processes that allow for the assimilation of ammonium into plants?
What are the roles of glutamate dehydrogenase, aspartate aminotransferase, and asparagine synthase?
What is the role of aminotransferases in amino acid metabolism?
What is biological nitrogen fixation?
What is the structure root nodules and how are they involved in biological nitrogen fixation?
How are root nodules formed in nitrogen-fixing plants and what is their relationship with nitrogen-fixing bacteria?
What are rhizobia?
What are bacteroids?
What is the structure and function of nitrogenase?
What is the role of leghemoglobin in regulating oxygen levels in root nodules?
What are amides?
