有迹象表明，多效性植物激素实际上可能通过激活酶来发挥作用，这些酶从细胞壁释放出这些更为特殊的化学信使。

There are indications that pleiotropic plant hormones may actually function by activating the enzymes that release these other, more specific chemical messengers from the cell wall.

代谢紊乱，如将清除淤血，细胞组织被激活酶的生产和增强(擦伤)。

Metabolic disturbances, such as extravasated blood (bruising) will be scavenged, cell tissues are activated and production of enzymes is enhanced.

我们也知道，大脑和脑脊髓液中的维他命 D 激活酶和失效酶涉及到神经传递素合成与神经生长。

We also know vitamin D activates and deactivates enzymes in the brain and the cerebrospinal fluid that are involved in neurotransmitter synthesis and nerve growth.

These are molecules that exist naturally in cell membranes and are activated by certain enzymes and kinases generated by receptors.

这些分子存在于细胞膜表面,能被受体激活的某种酶或激酶所活化

You then denature again, each one of these strands gets separated, primers bind, turn on the polymerase, a new strand is made.

然后你可以再次使产物链变性,使各链解旋,再结合引物,激活聚合酶,再生成新链

So, these are receptors, for example, that bind the ligand and then liberate an enzyme which promotes some sort of reaction inside the cell, often it's kinases but doesn't have to be.

例如,这里是受体,与配体相结合,激活一种酶,这种酶能够催化细胞内的某些反应,这些酶通常都是激酶,但不全是
