And then, of course, not just whether the reaction will occur but, how fast it occurs is really important.

当然，我们不光要研究一个反应会不会发生,反应速率多块也是很重要的研究问题。

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。
