And each of those hemoglobins can bind to four oxygen molecules.

而一个血红蛋白能与4个氧分子结合。

But that doesn't tell us how many oxygen molecules there are.

但这并没有告诉我们有多少氧分子。

So each hemoglobin can carry four oxygen molecules when it's fully saturated.

所以在饱和时，每一个血红蛋白可以携带四个氧分子。

Oxygen molecules emit a green or red color. And nytrogen emits pinks, blues and violets.

氧分子发出绿光或红光。氮分子发出粉光，蓝光和紫光。

When an empty hemoglobin runs into an oxygen molecule, things are a little awkward.

当一个空的血红蛋白碰到一个氧分子，事情就有点尴尬了。

So, each red blood cell can carry millions of oxygen molecules when it's fully loaded.

所以，当满载时，一个红细胞可以携带数百万个氧分子。

During an oxidative burst, the neutrophil produces lots of highly reactive oxygen molecules like hydrogen peroxide.

在一次氧化爆发中，中性粒细胞会产生大量高活性氧分子，如过氧化氢。

Every second, trillions of oxygen molecules fuse into helium molecules in a process called nuclear fusion.

每一秒钟，就有数万亿氧分子与氦分子发生结合。这一过程叫做核聚变。

Most important among these are oxygen molecules, which bind to the hemoglobin in your red blood cells.

其中最重要的就是氧分子，氧分子与红细胞中的血红蛋白结合。

It would get even worse once you realized that you can't force oxygen molecules down into your lungs.

这将会更糟，一旦你意识到，不能将氧分子吸入到肺里。

Copper ions do this by interacting with oxygen and changing the oxygen molecules. As a result, the virus cells cannot mutate.

铜离子能与氧化合并改变氧分子结构，这样病毒细胞就无法突变。

The hydrogen molecule binds with the oxygen molecule.

【bind】氢分子会和氧分子结合。

So, in a sense, each oxygen molecule makes a voyage.

所以，在某种意义上，每一个氧分子都在移动。

An example is H2O for water. Water has two hydrogen molecules and one oxygen molecule.

一个例子是 H2O 代表水。水有两个氢分子和一个氧分子。

And the souls were three-atom oxygen molecules of the stuff of ozone...

灵魂们组成了臭氧。

Stuff like nitrogen molecules, carbon dioxide ... MATT O'DOWD: Oxygen molecules.

安妮：氮分子、二氧化碳之类的东西… … 马特·奥多德：氧分子。

Oxygen molecules in the air come in two varieties. Most have a pair of atoms but some, known as ozone, have three.

空气中的氧分子有两种，大多数都有一对原子，但也有一些被称为臭氧的有三个原子。

But with no photosynthesis happening, they end up passing the unused energy along to oxygen molecules which become dangerously reactive when energized.

但由于没有发生光合作用，它们最终将未使用的能量传递给了氧分子，此时氧分子一旦被激发会变得非常危险。

In the following discussion of gas exchange, imagine yourself as an oxygen molecule going to work.

在以下有关气体交换的讨论中，将自己想象为一个将起作用的氧分子。

Now at this pressure, not enough oxygen molecules can force their way into your blood in your lungs.

在这种压力下，没有足够的氧分子能够进入肺部的血液。
