I know it's possible to induce chemical reactions, but these are exceptions. This is not the norm.
我知道催化化学反应是可能的，但是那些是特例，不是常规情况。
-
She needs to know this enzyme works by both acid base chemistry, and oxidation reduction.
她要知道酶催化，她需要知道这种酶,在酸碱环境下的反应和氧化还原反应。
-
He invented ammonia synthesis with catalysis by iron.
它发现了铁催化合成氨的催化反应。
-
Enzymes work best, enzymes are proteins that catalyze chemical reactions and our bodies operate by elaborate networks of chemical reactions, When we're off from that temperature then they don't work properly.
举酶这个例子再好不过,酶是一种具有催化作用的蛋白质,人体依靠精密复杂的化学反应网络来运转,如果我们体温与之相差较大,这些酶就不能正常工作
-
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
-
A reaction performed by one enzyme creates a product that stimulates another enzyme that creates a product, and stimulates another enzyme, and through this cascade of reactions you amplify and carry the signal forward.
一种酶催化生成的产物会活化另一种酶,而它催化的产物又能激活其他酶,催化反应生成另一种产物,通过这层层反应,信号被放大,并不断向前传递
-
If that protein is an enzyme then you've and you've switched it from an 'off' position where it's not catalyzing a reaction to an 'on' position where it is, you've changed the biochemical state of the cell, you've changed the chemical reactions that can occur within the cell, and you've changed its behavior.
如果这种蛋白是一种酶的话,你就能够将酶从无催化作用的静息态,激活至能催化反应的激活态,你改变了细胞的生化状态,也改变了细胞内发生的化学反应,改变了细胞的行为
-
It performs a chemical reaction on the protein, taking a phosphorous from ATP and moving that phosphorous onto the protein.
它能够催化蛋白参与如下反应,即将ATP上的一个磷酸基团,转移到蛋白质上
-
It gets produced in response to a signal so there's a binding of a ligand to a receptor, the enzyme that does this conversion is activated and more cycle AMP is released.
这类分子的产生是对信号做出的一种反应,当配体和受体结合时,催化这种转化过程的酶被激活,更多的cAMP释放出来
