WebFree ammonium ions are produced and consumed during cell metabolism. Glutamine synthetase utilizes free ammonium ions to produce glutamine in the cytosol whereas glutaminase and glutamate dehydrogenase generate free ammonium ions in the mitochondria from glutamine and glutamate, respectively. Ammoni … WebTherefore, ammonia excretion is most common in aquatic species. Many invertebrates release ammonia across the whole body surface. In fishes, most of the ammonia is lost as ammonium ions (NH4+) at the gill epithelium. Freshwater fishes are able to exchange NH4+ for Na+ from the environment, which helps maintain Na+ concentrations in body fluids.
WebFor most microorganism's ammonium is the preferred nitrogen source, which is a crucial building block of amino acids. Hence, most plants rely on ammonium and other nitrogenous wastes incorporated into the soil or into fertilizer. On the other hand, as high concentrations of ammonium are toxic, ammonium has to be excreted as metabolic waste.
