Abstract : Algae are primary producers of primary products to the food chain. So deal with most of the algae carbon and nitrogen compounds are converted to simple sugars and proteins in algae, where you get them from several sources available in the natural environment. And nitrogen is found in the simple form of the natural environment in the form of nitrate No3, nitrite and No2, and ammonia NH4, and urea (NH2) 2CO, as well as in gaseous N2, NO, and dealt with the study: 1 - isolation of some local breeds of some types of single-cell green algae and purification. 2 - Study the different sources of nitrogen, which can be exploited by these algae. 3 - Study the impact of these nitrogen sources on the production of the cell to the primary task of some enzymes in the metabolic pathways of protein synthesis. 4 - a comparative study of the enzymatic properties of the enzyme nitrate reductase in algae and knowledge of the selected components, and various enzymatic annexes. Been isolated single-cell green algae which live in fresh water pools of water in the western region of Saudi Arabia. Found that the moss cells represents the three compounds, nitrate, nitrite and ammonia when it gives each and every one of them alone. Observed a period of recession in the representation of nitrate for a period of 2-1 hours when algal cells are transferred to developing urea or ammonia to the nutrient medium containing nitrate, and then began the representation of nitrates on a regular basis.
