In mammals, the urea cycle takes place primarily in the liver, and to a lesser extent in the kidney. Ammonia Toxicity Every amino acid contains at least one amino group. Therefore every amino acid degradation pathway has a key step where the amino group is removed. In short amino acid catabolism generates ammonia. Brain tissue

    4.B Why do you think that the adding of sodium acetoacetate resulted in a 50% decrease in renal ammonia production? Sodium acetoacetate addition would result in a decrease in renal ammonia production because of the adjustment to the pH levels that it has. This happens due to direct oxidation. Some of the dogs in this experiment became tolerant to the sodium acetoacetate so their doses were changed. The conclusion was that since quantities that were essentially equal in tolerance were given that direct

    NITROGRN METABOLISM IN ANIMALS: Excess amino groups of the body are converted into a single excretory end product. The excretory product of bony fishes is ammonia and are therefore called ammonotelic. Their liver releases ammonia into the blood stream which is then sent towards gills which quickly clear it. Terrestrial animals like human beings excrete urea and are called ureotelic. The excretory product of birds and reptiles is uric acid and thus are called uricotelic. Excretion of urea needs large
