Ammonia is less soluble than uric acid.
Mollusks have a unique way of excreting nitrogenous waste. It is processed in the excretory organ and released into the water.
The kidneys are the human organs responsible for excreting nitrogenous waste products. They filter blood to remove urea, creatinine, and ammonia, which are the byproducts of protein metabolism. These waste products are then excreted from the body in urine.
Excrete more frequently
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
Urea is the main nitrogenous waste in urine. It is an organic compound that is essential for metabolism in humans because it allows the kidneys to produce hyperosmotic urine.
A squid's kidney functions to filter waste and excess ions from the blood, regulating the balance of salts and fluids in the body. It also helps in maintaining the internal environment of the squid by excreting nitrogenous waste in the form of ammonia.
The primary by-product of protozoan excretion is ammonia
nitrogenous waste products are produced by animals. the nitrogenous waste products contain an amino group which remove an amino acid in the form of ammonia. the formation of ammonia from the amino acid is known as deamination which occurs in the liver. nitrogenous waste products can be removed in 3 forms ammonia uria and uric acid.
Tadpoles excrete ammonia and frogs excrete urea
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.
Most aquatic animals, such as fish and marine invertebrates, excrete their nitrogenous waste mainly as ammonia. Ammonia is highly soluble in water and can be easily released through their gills or directly into the environment. This adaptation is beneficial in aquatic environments where water is readily available to dilute and remove toxic ammonia.
They've lost the subsequent enzymes required for catalyzing the synthesis of urea into ammonia.
