Why do animals excrete waste material
Answers
Answer:
primary nitrogenous waste product, they are called ureotelic animals. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals. It is the main nitrogen-containing substance in the urine of mammals.
Explanation:
Ureotelic animals, which includes mammals, produce urea as the main nitrogenous waste material.
2 NH3 + CO2 + 3 ATP + H2O → H2N-CO-NH2 + 2 ADP + 4 Pi + AMP is the chemical reaction by which toxic ammonia is converted to urea.
The urea cycle involves the multi-step conversion (carried out by five different enzymes ) of the amino acid L- ornithine into different intermediates before being regenerated.
Key Terms
ureotelic: animals that secrete urea as the primary nitrogenous waste material
ornithine: an amino acid, which acts as an intermediate in the biosynthesis of urea
urea: a water-soluble organic compound, CO(NH2)2, formed by the metabolism of proteins and excreted in the urine
Answer:
Explanation:
Because they also have digestive system as like human .
