The daily metabolic CO. production obligates the formation of some 15 mol of carbonic acid; normally expiration matches cellular CO. production so the H. homeostais is not threatened by this volatile a

A perplexing problem has been the observation that despite an increase in renal ammoniagenesis from glutamine known to occur in acidosis in vivo, glutamine metabolism in vitro was depressed by acid pH [1–3], probably by inhibition of phosphate-dependent glutaminase [4]. Although glutamine

Enzymes of Renal Glutamine Metabolismsis (Tannen 1978, Kovacevic and McGivan 1983). The amide and amine nitrogens of glutamine are released as ammonium ions. The increased ammoniagenesis provides an expendable cation which facilitates the excretion of anions and titratable acids without depleting the body’s supply of sodium and potassi
