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.

Just like, you might say, the old regime in France, the old aristocratic society existing before the revolution, tended to produce a very different kind of soul, a very different kind of individual.
就像法国旧时的政体，存在革命之前的,旧时贵族社会，倾向于催化一种非常不同的灵魂，一种非常不同的个体。
-
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
