题目 What is a reactant? 相关知识点: 试题来源: 解析 The substances undergoing reaction 反馈 收藏
In this example, A and B are the reactants and C is the product. There do not have to be multiple reactants in a reaction, however. In adecomposition reaction, such as: C→ A + B C is the reactant, while A and B are the products. You can tell the reactants because they ar...
A. It is a product B. It is a reactant C. It is a catalyst D. It has no role 相关知识点: 试题来源: 解析 A。中文解析:氧气在光合作用中是产物,光合作用利用二氧化碳和水产生葡萄糖和氧气,选项 B 反应物是二氧化碳和水,选项 C 催化剂在光合作用中不存在,选项 D 说法错误。反馈...
In a reaction, if the particle size of the reactants is reduced, what will happen to the reaction rate? A. Decrease B. Increase C. Remain unchanged D. Depend on the reaction 相关知识点: 试题来源: 解析 B。解析:减小反应物的颗粒大小可以增加反应物的表面积,从而增加反应速率。

Define what a substrate is and describe, in general, how enzymes act upon them. What is the reactant of an enzyme-catalyzed reaction called? What are the components of enzymatic reactions? Explain why the enzyme function varied with substrate concentration before the catalase concentration was satu...
in the process regenerating the catalyst. The following is a typical reaction scheme where C represents the catalyst A and B are reactants D is the product of the reaction of A and B: A + C → AC (1) B + AC → ABC (2) ABC → CD (3) CD → C + D (4) Although...

To date, it has been accepted that this effect is due to excess developed on negatively charged surfaces and to the subsequent transfer of these to the reactants in solution. The present study demonstrates that this view is incorrect and, in reality, the reactions are driven by mechano...
