The enzyme luciferase causes a chemical reaction.

酶荧光素酶引起。

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

酶是加快的物质——在这个例子中，就是破坏塑料。

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

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

Enzymes are complex proteins that make many chemical reactions possible.

酶是使许多成为可能的复杂蛋白质。

And in biochemistry and enzymology, enzymes have to be able to undergo conformational changes, right?

在生物和酶中， 酶必须能够发生构象变，对吧？

The same way that protein enzymes can do all kinds of chemical reactions, RNA enzymes–called ribozymes–can work life's machinery too.

就像蛋白质酶可以进行各种一样，RNA 酶（称为核酶）也可以驱动生命机器。

So I was looking into that, but there's not a bunch of information on the chemistry of that enzyme or anything about what's happening.

所以我在研究这个，但关于那种酶的性质或者相关过程的信息并不多。

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）与 DNA（存储信息）编码的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.

所有这些粉碎的目标是通过将食物分解成越来越小的碎片来增加食物的表面积，为它在第四步遇到更多的酶做好准备：消。

" 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， 然后不断添加物质， 直到找到一种抑制酶的物质，” 哈佛大神家鲁迪·坦齐（Rudy Tanzi）博士说， 他的实验室揭示了阿尔茨海默病遗传的关键方面。
