动物细胞和植物细胞都有细胞膜。
Animal and plant cells have cell membranes.
《TED教育》《TED-Ed》
就像任何细胞随着时间老化。
Just like any simple cell going through time.
《超体》《Lucy》
细胞膜上有很多突出的部分。
The cell membrane is covered with tiny projections.
《TED教育》《TED-Ed》
一般来说,细胞分裂遵循一个叫做“细胞周期”的有序的进程,也就是一个细胞的生命周期。
Normally, cell division follows an orderly process called the cell cycle, which is basically the life cycle of a cell.
《TED教育》《TED-Ed》
它假装是一个朋友,连到细胞膜上的一个突出部分,然后细胞让它穿过细胞膜进来。
Pretending to be a friend, it attaches to a projection on the cell membrane, and the cell brings it through the cell membrane and inside.
《TED教育》《TED-Ed》
之后它们把其中的一块放到细胞膜外面,这样细胞就可以警示它旁边的细胞:有入侵者。
They then send one of the pieces back through the cell membrane, where the cell displays it to warn neighboring cells about the invader.
《TED教育》《TED-Ed》
电脉冲,每个细胞都懂得互相沟通。
Electrical impulses. Every cell knows and talks to every other cell.
《超体》《Lucy》
你身体里的每一个细胞都是被细胞膜所包起来。那是由脂肪和蛋白质组成的一层即厚又软的物质,包围着并保护着细胞内部。
Each cell in your body is surrounded by a cell membrane, a thick flexible layer made of fats and proteins, that surrounds and protects the inner components.
《TED教育》《TED-Ed》
它们都有用处的,比如帮助细胞吸附住临近的细胞,或帮细胞链接上营养物质。
They all have functions, like helping cells adhere to their neighbors or binding to nutrients the cell will need.
《TED教育》《TED-Ed》
在细胞周期内有一系列的检验点,是诸如由乳腺癌1号基因制造的蛋白质调节细胞分裂速度的地方。
Within the cell cycle is a series of checkpoints, where proteins, such as the one produced by BRCA1, regulate how fast the cell may proceed.
《TED教育》《TED-Ed》
包在一个由细胞膜物质组成的泡泡里,高基式体也会给抗体指示,告诉它怎么去细胞的边缘。
Enclosed in a bubble made of the same material as the cell membrane, the golgi apparatus also gives the antibody directions, telling it how to get to the edge of the cell.
《TED教育》《TED-Ed》
但是只有植物细胞有细胞壁,当中坚硬的纤维素给植物制造了他的结构。
Only plant cells have a cell wall, which is made of rigid cellulose that gives the plant structure.
《TED教育》《TED-Ed》
但在那之前,抗体必须得离开细胞。
But before it can do that, the antibody needs to leave the cell.
《TED教育》《TED-Ed》
它们中的某些在调节细胞周期上比其他要更高效。
Some regulate the cell cycle more effectively than others.
《TED教育》《TED-Ed》
细胞射出抗体,然后抗体去找那病毒。
The cell ejects the antibody, and it heads out to track down the virus.
《TED教育》《TED-Ed》
肿瘤抑制基因参与控制细胞分裂速度。
Tumor suppressor genes are involved in regulating how fast a cell divides.
《TED教育》《TED-Ed》
旁边一个细胞看到了这个警示,立刻开始行动。
A nearby cell sees the warning and immediately goes into action.
《TED教育》《TED-Ed》
在你身体的每个细胞内,乳腺癌1号基因有两个副本。
You have two copies of the BRCA1 gene in every cell of your body.
《TED教育》《TED-Ed》
当它到了那里,包着抗体的泡泡融入细胞膜。
When it gets there, the bubble surrounding the antibody fuses to the cell membrane.
《TED教育》《TED-Ed》
这种“多余”其实是件好事,因为你虽然只需要一个乳腺癌1号基因工作就能控制细胞周期。
This redundancy is a good thing because you only need one functioning BRCA1 gene in a cell to regulate the cell cycle.
