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.
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 does the liver change ammonia into urea?
Ammonia is a breakdown product of proteins that is toxic to vertebrates. The body needs to get ammonia out of the body. By itself, ammonia is a small volatile molecule that will leak back and forth through cell and vessel membranes, making it hard for it to be gathered and excreted. Urea is made of two ammonia molecules. Because it is bigger, it is no longer volatile and cannot pass through membranes without special channels or transporters. This allows it to me concentrated in the urine for excretion from the body.
The sequencce of removing ammonia from the body is?
Ammonia is part of an amino group which is highly toxic thus cannot be allowed directly into the blood to travel from liver to kidney. It must first be converted into urea or uric acid a less toxic form. It can then travel to the kidney where it is filtered and then eliminated from the body. The term for breaking down the amino group to form ammonia is called deamination.

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.
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.
Is urea toxic?
Urea is used in fertilizers and is not considered toxic. Ammonia is toxic and is what converts readily to urea.
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.
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.
What converts ammonia wastes from the cells in urea?
The liver converts ammonia into urea through a series of chemical reactions in a process called the urea cycle. Urea is less toxic than ammonia and can be safely excreted by the kidneys in the urine.
Does the liver convert toxic ammonia into harmless urea?
Yes.
If human urine is allowed to stand for sometime it semelles strongly of ammonia . why?
Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide that is found in Urine. Dehydration causes your urine to be more concentrated and may have a stronger smell than normal,
Is there ammonia in the urine of German people?
No they do not. Humans does not contain ammonia in urine.
