Plants also convert carbon dioxide into different forms of carbon-containing molecules and the conversion process used relies on the very same enzyme that works in humans.

植物也会将二氧化碳转化成不同形式的含碳分子，而转化过程所使用的酶与人体内的酶完全相同。

But if a more complicated series of reactions is required, or the enzyme in the process is used up during conversion and needs to be regenerated, it is time to reach for a microbe.

但如果反应涉及一系列更复杂的变化，或是在转化中酶会被消耗殆尽，需要再次添加，这时就要微生物来帮忙了。

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
