分子不仅仅是一堆原子的集合，相比能量、力和场等抽象概念，它们以一种更加实体化更加多样化的形式出现在我们面前。

Molecules are more than the sum of their constituent atoms, and they connect with our senses in ways that are much more tangible and diverse than abstract notions of energy, forces and fields.

在这个初步概念的证明论证中，选择了两个染色分子，因为它们大小相似，易于检测。

In this initial proof-of-concept demonstration, the molecules selected were two dyes, chosen because of their similar size and ease of detection.

所以动理学的关键概念在于,速率依赖于多少分子,能够到达这里。

So the idea in the context of kinetics is that the rate depends on how many molecules can get up here.

Since then, since we know about atoms and molecules now, we can rationalize the concepts of thermodynamics using microscopic properties, 62 and if you are going to take 5.62, that's what you'd learn about.

既然我们现在已经知道了原子和分子,的概念），我们可以用,微观属性,来阐释热力学中的概念，如果你会选修5。,-那是你将要学到的。

This is a new concept, receptors don't have to be these molecules on cell surface, there can be receptors that exist in other places within the cell.

这是一个新概念,受体分子不一定只存在于细胞表面,它们也可以存在于细胞内其它地方
