Excretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.
Uric acid. Humans also excrete a second nitrogenous waste, uric acid. It is the product of nucleic acid, not protein, metabolism. It is produced within peroxisomes. 1  contribute to the formation of kidney stones; 2  produce the excruciating pain of gout when deposited in the joints.ost of our nitrogenous waste comes from the breakdown of amino acids. Deamination of amino acids results in the production of ammonia (NH3). However, the liver contains a system of carrier molecules and enzymes which quickly converts the ammonia (and carbon dioxide) into urea.
