The enzyme luciferase causes a chemical reaction.

酶荧光素酶引起化反应。

Enzymes are things that help chemical processes happen more quickly — in this case, destroying plastic.

酶是加快化反应质——在这个例子中，就是破坏塑料。

Enzymes are complex proteins that make many chemical reactions possible.

酶是使许多化反应成为可能复杂蛋白质。

However, RNA can also act as enzymes to speed up chemical reactions, and in many viruses, they have RNA instead of DNA.

而，RNA 也可以用酶来加速化反应，在许多病毒中，它们只有 RNA 而非 DNA。

The complex arrangement whereby proteinaceous enzymes (which orchestrate a cell's chemistry) are encoded by DNA (which does the information storage) could not have appeared from nothing.

蛋白质酶（调节细胞化反应）与 DNA（存储信息）编码复杂结构不可能凭空出现。

The goal of all this pulverization is to increase the surface area of that bite of food by breaking it down into increasingly tiny pieces, to prepare it to encounter more enzymes in step four: chemical digestion.

所有这些粉碎目标是通过将分解成越来越小碎片来增加表面积，为它在第四步遇到更多酶做好准备：化消化。

" You can take the protease, put it in a test tube and keep adding chemicals until you find one that inhibits the enzyme, " says Dr. Rudy Tanzi, a Harvard neurologist whose lab unraveled key aspects of the genetics of Alzheimer's.

“你可以服用蛋白酶， 把它放在试管里， 后不断添加化质， 直到找到一种抑制酶化质，” 哈佛大神经家鲁迪·坦齐（Rudy Tanzi）博士说， 他实验室揭示了阿尔茨海默病遗传关键方面。
