Factors which determine the pH at the surface include the pH in the bulk solution and the release of H+ ions in the enzyme-catalyzed reaction. The latter causes a lowering of pH at the surface, causing the reaction rate to differ from that computed assuming an equilibrium distribution of ...
A. decreasing the activation energy. B. decreasing the amount of free energy released. C. increasing the activation energy. D. increasing the amount of free energy released. E. increasing the energy of the transition state. 相关知识点: 试题...
The rates of enzyme reactions fall within a relatively narrow range. To estimate the rate enhancements produced by enzymes, and their expected affinities for transition state analog inhibitors, it is necessary to measure the rates of the corresponding reactions in water in the absence of a catalyst...
Method and apparatus for governing the reaction rate of enzymatic reactions Heterogeneous enzymatic catalysis is carried out by means of an enzymatic electrode comprising an enzyme fixed to a solid, conductive support. To govern the reaction rate during continuous transformation of a substrate, the enzy...
To quantify the reaction rate of the enzymatic hydrolysis of nylons at the surface of solid polymers, we prepared a thin layer of nylons on the bottom surface of each well in a polystyrene-based micro-assay plate. The thickness of the nylon layer was monitored by imaging analysis of the ...

The value of the parameters in the model (i.e., the mass transfer coefficient of substrate dissolution ( k L), the substrate solubility, and the rate constant for the enzymatic reaction) were determined in separate experiments. Using these parameter values, the model gave a good quantitative ...
Measurement of enzyme activity in a Clinicon reaction rate analyser was carried out in two ways: one method was based on absolute calibration and the other used an enzyme standard which involved adjustment of results according to the value for the standard obtained in each batch. Batch calibration...

We, therefore, characterised the effect of varying the total template concentration and exonuclease concentration on the rate of the autocatalytic reaction (Fig. 4) in buffer solution and when the reaction was localised within the proteinosomes. Fig. 4: Characterisation of autocatalytic PEN DNA ...
