Unit 1 1. A full appreciation of the physiology of a living organism must be based on a sound knowledge of its anatomy. Anatomy does not merely study the separation of parts, but the accurate description of the morphologies and functions of different organs. 对生物生理学的全面了解必须基于解剖学的系统知识。解剖学不仅仅是研究 人体各部分的分离；还要准确的描述各个器官的形态和生理功能。 2. Our daily food intake must match requirements and any excess must be excreted for balance to be maintained. 我们每天摄入的事物必须满足需要；任何多余的东西必须排出体外才能维持 平衡。 3. The process of stabilization of the internal environment is called homeostasis and is essential if the cells of the body are to function normally. 内环境稳定的过程称之为体内平衡；体内平衡也是机体的细胞正常发挥作用所必 不可少的。 4. Human cells have the ability to break down large molecules to smaller ones to liberate sufficient energy for their activities. 人类细胞有将大分子分解成小分子的能力；从而为自身活动释放足够的能量。 5. As long as normal conditions are maintained in this internal environment, the cells of the body continue to live and function properly. 只要这种内环境正常的条件得以维持；机体的细胞就能继续生存并发挥正常 功能。 Unit 2 1. Biochemistry asks how the thousands of different biomolecules interact with each other to confer the remarkable properties of living organisms. 生物化学探寻的是数千种不同的生物分子如何相互作用；以赋予生物体具备显著的特性。 2. Enzymes are catalysts that accelerate the rates of biological reactions. Each enzyme is very specific in its function and acts only in a particular metabolic reaction. 酶是能加速生物学反应速率的催化剂。每一种酶都有专一的功能并且仅在特定代谢反应 中发挥作用。 3. One of the most fruitful approaches to understand biological phenomena has been to purify an individual chemical component, such as a protein, from a living organism and to characterize its chemical structure or catalytic activity. 用以了解生物学现象的最有效的方法之一是从生物体中纯化出单一化学成分；例如蛋白 质；并对其化学结构或催化活性进行表征。 4. The chemical principles that govern the properties of biological molecules include the covalent bonding of carbon with itself and with other elements
