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

内质网会将核糖合成的蛋白质运到高尔基。

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.

与真核细相比，细菌的结构简单很多：缺少细核及膜包被的细器，例如线粒、内质网与高尔基。

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，它最终会触发与细网上的钙通道相连的电压敏感蛋白。

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抗蛋白酶可聚集并阻塞于肝细内质网中，即α-1抗蛋白酶产生的地方，导致其中一部分肝细死亡。

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，大多数的细内钙储存在细器中，比如线粒、内质网，当需要的时候，它们会被选择性地释放。

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

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

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

一些核糖游离于细质中，而另一些则附着在内质网上。

The tissue is also exposed to diastase, which is an enzyme that normally destroys alpha-1 antitrypsin, but since alpha-1 antitrypsin's stuck and hidden away in the endoplasmic reticulum, diastase can't get to it and so it's diastase resistant.

该活检组织也被施用淀粉酶；淀粉酶通常用于水解α-1抗蛋白酶，但由于α-1抗蛋白酶阻塞、隐藏于内质网中，淀粉酶触及不了，因此产生淀粉酶抵抗。

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网的时候。

Remember that the " egg" is still just a secondary oocyte here, and hasn't completed meiosis. As the sperm delivers its payload, it causes a flash of calcium ions from the oocyte's endoplasmic reticulum.

请记住，“卵子”在这里仍然只是一个次级卵母细，还没有完成减数分裂。当精子传递其有效载荷时，它会从卵母细的内质网中产生钙离子闪。

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网中的钙。

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.

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

But soon the fiber slides back down into the relaxation period, when the calcium gets pumped back into the sarcoplasmic reticulum, and the actin and myosin stop the binding cycle, and the muscle relaxes.

但很快，纤维滑回松弛期，此时钙被泵入网，动蛋白和球蛋白停止结合循环，肉放松。

And so what does the rough endoplasmic reticulum do?

糙内质网的功能是什么？

Golgi went on to propose that the brain is made up of a single network or reticulum of nerve fibres, through which signals pass unimpeded.

高尔基进而提出， 大脑由单一的神经纤维网络或网状结构组成，信号可以无阻碍地通过这一网络。

The one that I want to talk about more specifically is called endoplasmic reticulum.

我特别想谈论的是内质网。

And so endoplasmic reticulum is just one organelle inside eukaryotic cells.

内质网只是真核细内的一种细器。

So if we work outward from that, right on the outside of that we have the ER, endoplasmic reticulum.

因此，如果我们从那里向外看，紧挨着外的就是内质网（ER）。

Well in general it takes information that's produced in the endoplasmic reticulum and then it shifts those to different parts of the cell.

总的来说，它会把内质网产生的信息转移到细的不同部分。

Endoplasmic reticulum has two different parts to it.

内质网有两个不同的部分。
