1.nucleotide 核苷 2.isomerase异构酶 3.ribosome核糖体
二、1. The study of biochemistry shows how the collections of inanimate molecules that consitute living organisms interact to maintain and perpetuate life animated solely by the physical and chemical laws that govern the nonliving universe.生物化学的研究揭示了组成生命体的无生命分子是如何根据仅适用于无生命的自然界万物的物理和化学定律，通过聚集和相互作用，维持和保持生命活力。
2. Proteins have the most dynamic and diverse role of any macromolecule in the body, catalysing biochemical reactions, forming receptors and channels in membranes, providing intracellular and extracellular scaffolding support, and transporting molecules within a cell or from one organ to another. 蛋白质是人体所有高分子中，最活跃也最多作用：催成生化反应，构成膜上的受体和通道，为胞内和胞外的折叠提供支持，在细胞内或器官之间转运分子。
3.The plasma membrane defines the periphery of the cell, separating its contents from the surroundings.质膜精确地界定了细胞的边缘，把细胞本身的内容物与外环境分开。

在人体所有高分子中，蛋白质是最活跃多变的且作用也最多：催成生化反应，构成膈膜的受体与通道，为细胞内外的折叠提供支持，在细胞内或器官之间转运分子。
3.The plasma membrane defines the periphery of the cell, separating its contents from the surroundings.
浆膜精确界定了细胞的外围，把细胞自身的内容物与外环境分开。
這個。。這個。。仔細看了下，實在不懂。遺憾。
