Glycolysis and Respiration in Yeasts: the Effect of Ammonium Ions Studied by Mass Spectrometry Free

Abstract

Addition of NH in the presence of glucose to washed suspensions of or greatly increased glycolytic CO production and slightly stimulated respiration. In all three organisms the ammonium ion effect was distinguishable from the effect of an uncoupler of aerobic energy conservation (carbonyl cyanide -chlorophenylhydrazone; CCCP). The Pasteur effect (aerobic inhibition of glycolysis) in the fermentative yeasts also proceeded independently of the ammonium ion effect. Possible control mechanisms are discussed.
