Kinetic Studies on Yeast Growth (part 4)

Kinetic studies of yeast hexokinase.

The mechanism of calf brain hexokinase has recently been studied in our laboratory (1). It was concluded from kinetic experiments that adenosine diphosphate (ADP) dissociates from the enzyme before addition of substrate glucose. This hypothesis was supported by kinetic studies of n-mannose, ADP, and glucose g-phosphate inhibition. The experiments appear to lend credence to theories in which an ...

Kinetic and thermodynamic studies of adsorption of 4-chloro-2-nitrophenol on nano- Ti02

Adsorption capacity of 4-chloro-2-nitrophenol (4C2NP) onto nano-Ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP adsorptionwere found to be initial pH z 2, nano-TiO2 closer- 0.01 g and equilibrium time 1 h. The adsorptionkine...

Studies of the kinetic mechanism of orotate phosphoribosyltransferase from yeast.

Kinetic analysis of the reaction catalyzed by a homogeneous preparation of orotate phosphoribosyltransferase from yeast has revealed that the reaction may proceed through the use of a Bi Bi Ping Pong kinetic mechanism. This interpretation is based on initial rate measurements and product inhibition studies of both the forward phosphoribosyl transfer and the reverse pyrophosphorolysis reactions ...

Studies on Yeast Zymin

In previous communications by the authors (1935) data were presented on the effect of some electrolytes, and of ethanol, upon the evolution of carbon dioxide from glucose by yeast aymin. The electrolytes, in appropriate concentrations, stimulate the rate of evolution of the gas. The zymin is very sensitive to ethanol. The addition of phosphate does not decrease the sensitivity toward ethanol, w...
