Which Is Least Toxic Co2 Or Uric Acid?

Which excretory material is least toxic?

Ammonia is the most toxic, followed by urea and uric acid.

The latter is the least toxic..

What is the main nitrogenous waste excreted by birds?

Nitrogenous Waste in Birds and Reptiles: Uric Acid Uric acid is a compound similar to purines found in nucleic acids. It is water insoluble and tends to form a white paste or powder; it is excreted by birds, insects, and reptiles.

Which of the following is the least toxic of nitrogenous wastes?

Ammonia is very toxic to the body. Hence it is converted in the liver to less toxic products like urea and uric acid. The uric acid is the least toxic metabolic product of protein metabolism, which gets excreted by urine.

What is the most toxic excretory product?

AmmoniaAmmonia is the primary excretory material of many aquatic freshwater forms. It is most toxic waste material which requires large amount of water for its excretion.

What is the advantage of excreting urea rather than ammonia?

worktest questions for Unit 4QuestionThe advantage of excreting wastes as urea rather than as ammonia is that:BBirds secrete uric acid as their nitrogenous waste because uric acid: A) allows birds to live in desert environmentsCWhich of the following nitrogenous wastes requires hardly any water for its excretion?E113 more rows

Which one is more toxic ammonia or urea?

Urea is a less toxic compound than ammonia; two nitrogen atoms are eliminated through it and less water is needed for its excretion. It requires 0.05 L of water to excrete 1 g of nitrogen, approximately only 10% of that required in ammonotelic organisms.

Why do birds excrete uric acid instead of urea?

Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. … Producing uric acid instead of urea is advantageous because it is less toxic and reduces water loss and the subsequent need for water.

Do humans excrete uric acid?

In normal humans, uric acid is excreted in urine. However, uric acid excretion may be impaired by kidney disease, leading to hyperuricemia [2].

Why Ammonia is highly toxic?

When excessive amounts of ammonia enter the central nervous system, the brain’s defences are severely challenged. – A complex molecular chain reaction is triggered when the brain is exposed to excessive levels of ammonia. We have found that ammonia short-circuits the transport of potassium into the brain’s glial cells.

What are Uricotelic animals give example?

Uricotelic organisms include terrestrial arthropods (including insects), lizards, snakes, and birds.

Which of the following is Ureotelic?

Ammonia produced by metabolism is converted into urea in the liver of these animals and released into the blood which is filtered and excreted out by the kidneys. Camel, whale (mammals), toad( terrestrial amphibian) and shark (marine fish) are examples of ureotelic animals.

Which is less toxic urea or uric acid?

Uric acid is also less toxic than ammonia or urea. It contains four nitrogen atoms; only a small amount of water is needed for its excretion.

Which is the most toxic product formed in animals?

AnswerAnswer:Ammonia is the most toxic excretory product formed in animals.Explanation:Excretory system of our body help in the removal of various waste material from our body such as ammonia,urea,uric acid. Ammonia is highly toxic among 3 of them.

Which of the following is least toxic?

Small amount of nitrogenous waste substances are also produced during the metabolism of nucleic acids. Ammonia is the most toxic, followed by urea and uric acid. The latter is the least toxic.

Is responsible for the recovery of water and sodium chloride from the urine?

The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine. This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as intake for survival.
