因为是研究者主动改变温度来观察对酶活性(因变量)的影响。选项A结果和选项B成果在这里不符合变量的概念;选项D因变量是受自变量影响而变化的,这里温度是自变量不是因变量。本题考查实验变量概念,词汇有“enzyme activity(酶活性)”,语法为简单的主系表结构。
The enzyme (urease) is immobilized on chemically modified glass beads and placed inside of the microreactor. In the case of microreactors measured at the elevated temperature ca. 37掳C, the enzyme activity was higher.Karol MALECHADorota PIJANOWSKA...
The hypothesis of an experiment on the effect of temperature on enzyme activity is that as the temperature rises, enzyme activity ___ until an optimal temperature is reached. A. decreases B. remains constant C. increases D. stops 相关

A method for thermally induced switching of enzyme activity has been developed, based on the site-directed conjugation of end-reactive temperature-responsive polymers to a unique cysteine (Cys) residue positioned near the enzyme active site. The reversible temperature-induced collapse of N,N-dimethylac...

Growth, anatomy and enzyme activity changes in maize roots induced by treatment of seeds with low-temperature plasma The seeds of Zea mays L. cv. KWS were exposed to low-temperature plasma (LTP) by using Diffuse Coplanar Surface Barrier Discharge (DCSBD) for 60 and 120 se... M Henselová...
For PFK and PK, season modified the relationship between growth rate and enzyme activity. This effect may be due to differences in the initial condition of the fish used for the experiments in the different seasons. Acclimation temperature only affected the activity of LDH, but its effect was ...
Then, optical density, enzyme activity, and productive rates for calcium carbonate were measured to analyze the influence of temperature. Finally, the effect of urea concentration on carbonate precipitation was studied by changing the urea concentration that was added during inoculation. The obtained ...
