这类物质一般是线粒体活动的副产品，但是通常都在泄露并造成伤害前被特殊的酶消灭——比如，它们可能损害细胞的DNA。

These are a normal by-product of mitochondrial activity, but are usually mopped up by special enzymes before they can escape and cause harm—for instance, by damaging a cell's DNA.

In some cells they're recycled, that is the cell is able to take up the neurotransmitter after it's released and restore it, but most often there are enzyme systems inside the pre-synaptic membrane where those neurotransmitters are synthesized.

在一些细胞中神经递质可以循环利用,这些细胞可以吸收,已经释放出的神经递质并重新储存起来,但更常见的是突触前膜中含有酶系统,在此合成神经递质
