Describe how inorganic nitrogen is assimilated into glutamate and the other 19 amino acids used for protein synthesis. What are the products of amino acid oxidation and how do humans dispose of their nitrogenous waste?
Homework Answers
nitrogen assimilation is the formation of organic nitrogen compounds present in the environment. Usually ammonium is the most preferred inorganic nitrogen source for microorganisms. ammonium assimilation requires the transport of this ion into the cells and its further incorporation into carbon skeletons.
urea is the product of amino acid oxidation.
when cells break down proteins, they produce nitrogenous wastes, such as urea. the excretory system in human serves to remove these nitrogenous waste products as well as excess salts and water from the body.
