The endoplasmic reticulum helps transport proteins made by the ribosomes to the Golgi apparatus.

内质网会将核糖体合成的蛋白质运到高尔基体。

Some ribosomes float free in the cytoplasm, while others are attached to the endoplasmic reticulum.

一些核糖体游离于细胞质中，而另一些则附着在内质网上。

And meanwhile, those calcium pumps are working hard to restock the calcium in the sarcoplasmic reticulum.

与此同时，这些钙泵正在努力补充肌浆网中的钙。

Because, remember, the relaxation period of a twitch is when all the calcium is being pumped back into the sarcoplasmic reticulum.

因为，记住，抽搐的放松期是所有的钙都被泵入肌浆网的时候。

There can be as many as 10 million ribosomes in a human cell, all studded along a ribbon-like structure, called the endoplasmic reticulum.

人类的细胞可能有多达千万个核糖体，沿着一个带状结构排列，这个带状结构称为内质网。

In addition, most of the intracellular calcium is stored within organelles like the mitochondria and smooth endoplasmic reticulum and is released selectively just when it's needed.

另外，大多数的细胞内钙储存在细胞器中，比如线粒体、光面内质网，当需要的时候，它们会被选择性地释放。

Misfolded alpha-1 antitrypsin can aggregate and get stuck in the endoplasmic reticulum of the liver hepatocytes where it's made, causing some of those cells to die.

错误折叠的α-1抗胰蛋白酶可聚集并阻塞于肝细胞内质网中，即α-1抗胰蛋白酶产生的地方，导致其中一部分肝细胞死亡。

When the action potential travels down one of those tubes, it eventually triggers the voltage-sensitive proteins that are linked to those calcium channels on the cell's sarcoplasmic reticulum.

当动作电位通过其中一个管子时，它最终会触发与细胞肌浆网上的钙通道相连的电压敏感蛋白。

When compared to eukaryotic cells, the structure of bacteria is less complex due to a lack of nucleus and membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi complexes.

与真核细胞相比，细菌的结构简单很多：缺少细胞核及膜包被的细胞器，例如线粒体、内质网与高尔基体。

And muscle cells also have their own version of an endoplasmic reticulum — the cell's transport and storage system — but in this case it's specialized, so it gets a special name: the sarcoplasmic reticulum.

肌肉细胞也有自己的内质网——细胞的运输和储存系统——但在这种情况下，它是专门化的，所以它有一个特殊的名字：肌质网。
