So, that's kinetics -- how fast a reaction will go, and from the perspective of someone who's a biochemist, I'm interested in kinetics and enzyme kinetics, and thinking about molecules that catalyze reactions in the body.

所以这就是动力学，一个反应发生的有多快,从一个生物化学家的角度,我喜欢研究动力学,酶动力学。

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
