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。
In this article, we will discuss the effect of pH and temperature on enzyme activity. Effect of pH on Enzyme Activity pH is a measure of the acidity or basicity of a solution. Enzymes have an optimal pH range at which they function most efficiently. This optimal pH range varies for ...

Usually, the effect of temperature on enzyme activity is irreversible. It could reflect different organic components being utilized by different microorganisms in different temperature ranges, but the substrates and process conditions determine the density and composition of microbial communities (Awasthi et...

The invention discloses a method of improving the enzyme activity of medium-temperature alpha-amylase. The method comprises the following steps: (1) inoculating a bacillus subtilis seed solution accounting for 2% of the total weight of a fermentation solution into a fermentation tank filled with ...
can regain their shape and function after denaturation if the denaturing agent is removed, and the presence of protein re-folding enzymes called molecular chaperones helps. However proteins denatured by heat do not renature, and heat is a reliable way to "kill" the activity of an enzyme....
