The assimilation of inorganic nitrogen in plants. The main enzymes involved are indicated in italics: NR nitrate reductase; NiR nitrite reductase; GS glutamine synthetase; GOGAT glutamate synthase. Ammonium is incorporated into organic molecules in the form of glutamine and glutamate through the combined action of the two enzymes GS and GOGAT in the plastid or chloroplast
