The actin cytoskeleton plays incredibly important roles in our cells.

白骨架在我们细胞中扮演着至关重要角色。

Unlike our skeletons, actin filaments are constantly being built and taken apart.

和我们骨架不同，白纤维（微丝） 一直在不停装和拆散。

Specifically, that club-headed myosin wants to get all up-close-and-personal with the actin.

具体来说，棒状头球白想近距离接触白。

In our muscle cells, actin structures form these regular filaments that look kind of like fabric.

在我们肉细胞中，白结构形成了这些看起来像布料规则纤维。

But you can't just breathe in the stuff you need to build DNA, or actin, or a phospholipid bilayer.

但是你无法靠呼吸来构建脱氧核糖核酸、白或磷脂双分子层所需东西。

They've got their own famous coupling — a pretty pair of tiny protein strands called actin and myosin.

它们有自己著名联结——一对漂亮微小白质链，叫做白和球白。

Like the actin and myosin in our muscles that enable us to move.

就像我们肉中白和球白一样，它们使我们能够移。

You actin' mighty happy this mornin', Miss Scarlett.

你好像很快乐 斯佳丽。

Soap? Deodorant? The toughest actin' Tinactin?

肥皂? 除臭剂? 还是药效最强牛皮癣喷雾?

Why? Why was she actin' out?

为什么 为什么她要出走？

See those funny big black-eyes folks we were runnin' around with actin' all crazy?

看到那些好玩黑眼睛村民来回游荡看上去像疯了一样?

This movement is powered by one of my favorite proteins called actin, which is part of what's known as the cytoskeleton.

它作由我最喜欢白之一，白驱，这种白是所谓 “细胞骨架”一部分。

They'll get a good bit o' actin' out of it an' there's nothin' children likes as much as play actin'.

他们会从中得到一些表演，没有什么比表演更让孩子们喜欢了。

Namely, actin is blocked by a couple of protein bodyguards — called tropomyosin and troponin — which keep getting in the way.

也就是说，白会白质保镖阻断——原球白和钙白——它们一直碍事。

" Bless us all, I can see tha' has a good bit o' play actin' to do, " said Susan Sowerby.

“保佑我们所有人，我看得出来你们有很多事要做，”苏珊·索尔比说。

They're divided lengthwise into segments called sarcomeres, which contain two even tinier strands of protein — two different kinds of myofilaments called actin and myosin.

它们在纵向上分成称为节部分，其中包含两股更小白质——两种不同丝称为白和球白。

A sarcomere contains both thin filaments, made up mostly of two light and twisty actin strands, and thick filaments, composed of thicker, lumpy-looking myosin strands.

节既包含细丝，主要由两条轻盈而扭曲白链成，也包含粗丝，由更厚、看起来块状球白链成。

When Martha suggested to me that I " kind o' notice the way Henry's actin', " I decided that Samson and his lordliness irked him.

当玛莎建议我“稍微注意一下亨利行为方式” 时，我认为参孙和他威严让他感到厌烦。

So after all that, with the myosin primed for action and the bodyguards out of the way, the myosin finally binds to actin, and it is beautiful.

经过这一切，当球白准备好行，保镖离开，球白最终与白结合，这真是太美了。

If another action potential travels down before that can happen, even more calcium gets released, which ends up exposing more actin for myosin to bind to, and that means more force in that fiber.

如果另一个作电位在此之前下降，更多钙释放出来，最终暴露出更多白来结合球白，这意味着纤维中有更多力量。
