Nitrogenous wastes such as ammonia, urea, and uric acid all result from?
Protein metabolism.
Is urea formaldehyde thermoset or thermoplastic?
Thermosetting
Why is ammonia itself not used as a fertilizer?
In some parts of the US, it is used as a common fertilizer material. Anhydrous ammonia (ammonia with all the water removed) is delivered in pressure tanks to the farmer, who then uses an implement behind a tractor to inject the ammonia about eight to ten inches deep into the soil.
Is urea and yellow 5 pork?
Urea is a chemical that is excreted in all mammals' urine. It is used in fertilizers, as a chemical feed stock for other syntheses, in the making of explosives, and in pollution reduction systems for diesel engines, among other things, but not is food. So there shouldn't be a problem even if it did come from pig urine. Further, for industrial purposes now, urea is synthesized from ammonia and carbon dioxide, and so does not derive from animal products at all. Yellow 5 is Tartrazine, a synthetic azo dye derived from petroleum. It is derived from raw chemicals, not from animal products.
What are precursors of urea synthesis?
All amino acids
Nitrogenous wastes such as ammonia, urea, and uric acid all result from?
Protein metabolism.
List three main nitrogenous waste products compare their toxicity and the amount of water that must be expelled in order to excrete each one?
The three main nitrogenous waste products are Ammonia, Urea and Uric Acid. Ammonia can only be tolerated at very low concentratisons, animals that excrete nitrogenous wastes as ammonia need access to lots of water. In this case ammonie excretion is most common in aquatic species. The ammonia molecules easily pass through membranes and are readily lost by diffusion to the watter surrounding the aquatic animal. In most vertebrates the ammoina release happens all across the whole body surface. In fishes, the ammonia is lost as ammonium ions (HH4+) across the epithelium of the gills. The kidneys excreet only minor amounts of the nitrogenous wastes. In freshwater fishes, the gille epithelium takes up Na+ from the water in exchange for NH4+, which helps to maintain a muchg higher Na+ concentration in the body fluids than in the surroundng water. Next we look at Urea, mammals, adult amphibians, sharks, and turtles excrete urea. This substance is produced in the vertebrate liver by a metabolic cycle that combines ammonia with carbon dioxide. Urea has a low toxicity, about 100,000 times less than that of ammonia. This allowes animals to transport and store urea safely at high concentrations. One of thie disadvantages of urea is that the animals must expand thir engergy to produce it from ammonia. Urea excretion requires much less water, becausemuch less water is lost when a given quantity of nitrogen is exvreted in a concentrates solution of urea rather than a dilute solution of ammonia. Insects, land snails, many reptiles, and birds, excrete uric acid. Urea and uric acid are like But unlike ammonia or urea, uric acid is largely insoluble in water and can be excreted as a semi solid paste with very little water loss. Uric acid is even more energetically expensive to produce than urea, requiring considerable ATP for synthesis from ammonia.
What do ammonia baking soda and Windex all have in common?
bases
Does everybody have ammonia in their bodies even girls?
There is some small quantity of ammonia in everyone's body, yes. It's a natural product of the breakdown of certain compounds, such as amino acids (found in all proteins). In humans, ammonia is mostly quickly converted to the less toxic compound urea.
What are the excretory product of the kidneys?
urine (urea, creatinine, bilirubin, and ammonia)
Of what value is urease to helicobacter?
H. pylori are able to fight the stomach acid with urease they release. Urease converts the urea in the stomach into bicarbonate and ammonia, which are strong bases. This creates a cloud of acid-neutralizing chemicals around the H. pylori, protecting it from stomach acid.
What all do reactions involving enzymes have in common?
Enzymes are substances produced by living organisms, which are designed to act as a catalyst in biochemical reactions.
What do all cell membranes have in common?
They all use little tiny enzymes to grow chloroplasts
Why is there urea in cows?
Urea is a byproduct of urine. All animals produce urea in their urine, not just cows.
Why are all enzymes catalysts but not all catalysts are enzymes?
