Urea enzymes and ammonia are both involved in the nitrogen metabolism of organisms. Urea enzymes help in urea synthesis or breakdown, while ammonia is a byproduct of nitrogen metabolism that needs to be efficiently processed or excreted from the body to prevent toxicity. Both play crucial roles in maintaining nitrogen balance in living organisms.
What else can I help you with?
What are precursors of urea synthesis?
All amino acids
Nitrogenous wastes such as ammonia, urea, and uric acid all result from?
the breakdown of proteins in the body. Ammonia is the most toxic waste product and is converted to urea in the liver for excretion. Urea is the main nitrogenous waste in mammals, while uric acid is prevalent in birds and reptiles.
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 formaldehyde thermoset or thermoplastic?
Thermosetting
Does 409 have ammonia?
Yes, 409 All Purpose Cleaner does not contain ammonia as an ingredient.
What do ammonia urea and enzymes have in common?
Ammonia, urea, and enzymes are all involved in biological processes. Ammonia and urea are nitrogenous waste products produced during the breakdown of proteins, while enzymes are proteins that catalyze chemical reactions in living organisms. Enzymes can be involved in the metabolism of ammonia and urea to regulate nitrogen metabolism in the body.

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.
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.
Of what value is urease to helicobacter?
Urease is essential for Helicobacter pylori because it helps the bacteria survive in the acidic environment of the stomach by hydrolyzing urea to produce ammonia. Ammonia helps neutralize the stomach acid, allowing H. pylori to colonize and persist in the gastric mucosa.
Why is there urea in cows?
Urea is a byproduct of urine. All animals produce urea in their urine, not just cows.
What do all cell membranes have in common?
They all use little tiny enzymes to grow chloroplasts
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 plants need ammonia (NH3) for in order to thrive?
Plants need ammonia (NH3) to absorb and use nitrogen, which is an essential nutrient for their growth and development. Nitrogen is a key component of proteins, enzymes, and chlorophyll, all of which are necessary for plant health and vitality.
