However, in the female group, the plasma arginase level increased with age (p = 0.05). Its biological significance was unclear. As a whole, the ELISA method for the measurement of arginase concentration in the body fluid is convenient and reliable.Soo-Ray...
Explain how the structure of an enzyme and substrate function. Include a specific example in your answer. How does the concentration of enzymes affect enzyme activity? Answer of the following question. Explain how an enzyme lowers the requ...
The activity can be monitored by measuring changes in concentration of substrates or products during the reaction. An activation coefficient can be deduced, which reflects the status of the enzyme investigated, and thus the vitamin status. Most assays are conducted with whole blood or the separated...
Though specific enzymes have specific substrate for their action. Their affinities for that particular substrate can be changed by different influencing factors . Factors that affect enzyme activity are – 1.Enzyme concentration- If the amount of substr
In a biphasic system the benzaldehyde is predominantly in the organic phase and the de facto substrate concentration in the buffer phase was calculated by determination of the partition coefficient MTBE-H2O of benzaldehyde. Each reaction was performed in duplicate as two different independent experiments...
定位到文章原句the researchers found a strong placebo effect, in the 35 volunteers who received the dummy capsules,the positive effects on perceived stress and fatigue,in the group of 35 who took the enzyme capsules were much greater,the enzyme appeared to boost concentration,cut feelings of weari...
If the optimal temperature for an enzyme is 35 degrees C and the optimal pH is 7.8 and the current conditions are 32 degrees and a pH of 8.5, which of the following would increase enzyme activity? a. Decrease substrate concentration b. 3 degree C increa ...
The fabricated EBFC had power densities of 15.26 to 38.33 nW/cm2 depending on the enzyme concentration in media supplemented with 25 mM glucose. Despite the low power density, the GDH-based EBFC showed increases in cell viability (~150%) and cell migration (~90%) with a relatively low...
(Chakraborty et al., 2016;Facin et al., 2019). In order to improve the immobilization efficiency, some parameters can be optimized during the adsorption, such as pH, temperature, contact time, initial enzyme concentration and ionic strength (Facin et al., 2019). The optimal parameter values ...
Enzyme Activity and Enzyme Concentration In principle, the amount of a biocatalyst may be expressed as a number of elementary entities, an amount of substance, a mass, or by a catalytic effect. In many cases, due to the lack of information or for practical reasons, the later route is used...
