How many times ammonia is more toxic than urea?
Ammonia is approximately 3 times more toxic than urea in terms of acute toxicity. Urea is less toxic to aquatic organisms compared to ammonia because it undergoes nitrification in water, converting it to nitrate which is less toxic.
Why ammonia is more toxic than urea?
Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.
Most toxic - urea NH3 NH4 or carbonic acid?
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
How many times urea is less toxic than ammonia?
Urea is approximately 1.5 times less toxic than ammonia. This is because urea is less alkaline compared to ammonia, which can cause burns and irritation. However, both substances can be toxic if ingested in large amounts.
Is urea more toxic thzn ammonia?
Urea is typically less toxic than ammonia. Ammonia is a direct irritant to the respiratory system and can cause damage upon inhalation, while urea is less likely to cause immediate harm. However, both substances can be harmful in high concentrations and should be handled with caution.

Why ammonia is more toxic than urea?
Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.
Why urea is more toxic than uric acid?
Urea is more toxic than uric acid primarily due to its higher solubility in water and its impact on cellular processes. Urea can disrupt osmotic balance, leading to cellular swelling and potential damage when present in high concentrations. In contrast, uric acid is less soluble and is excreted as a solid, which reduces its toxicity and allows for safer elimination of nitrogenous waste in organisms. Thus, the biochemical properties and excretion methods of these compounds contribute to their differing levels of toxicity.
The least toxic of nitrogenous wastes is?
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
The amino group that is removed from an amino acid during deamination is converted to the less toxic form of .?
The amino group that is removed from an amino acid during deamination is converted to the less toxic form of urea. This process primarily occurs in the liver, where ammonia, a toxic byproduct of amino acid breakdown, is converted into urea through the urea cycle. Urea is then excreted from the body via urine, helping to safely eliminate excess nitrogen.
Most toxic - urea NH3 NH4 or carbonic acid?
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
Is urea toxic?
Urea is used in fertilizers and is not considered toxic. Ammonia is toxic and is what converts readily to urea.
What are the three nitrogenous waste excreted by animals?
The three nitrogenous wastes excreted by animals are ammonia (most toxic, released by aquatic animals), urea (less toxic, excreted by mammals), and uric acid (least toxic, excreted by birds and reptiles).
How many times urea is less toxic than ammonia?
Urea is approximately 1.5 times less toxic than ammonia. This is because urea is less alkaline compared to ammonia, which can cause burns and irritation. However, both substances can be toxic if ingested in large amounts.
A nitrogenous waste that is less toxic than ammonia?
Urea is a nitrogenous waste that is less toxic than ammonia. It is produced in the liver as a byproduct of protein metabolism and is excreted by the kidneys in urine. Urea requires less water to be excreted compared to ammonia, making it a more efficient waste product for terrestrial animals.
What do kidneys excret?
Kidneys excrete urea which is a less concentrated form of uric acid and toxic waste .
The advantage of excreting wastes as urea rather than as ammonia is that?
Urea is less toxic than ammonia, making it safer to store in the body before excretion. It also requires less water to eliminate compared to ammonia, making it more energy-efficient for terrestrial animals. Additionally, the conversion of ammonia into urea consumes less energy, resulting in a net energy savings for the organism.
