2 Overview Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. It can also be defined as the study of energy relationships and energy transformations in living organisms. 生物能学是化学键的生化与参与接通和分断的发现在生物分子中的能量有关的部分。它也可以被定义为研究能量关系及生物体中的能量转换。

3 Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic processes that can lead to production and utilization of energy in forms such as ATP molecules. 生物能学是涉及通过生命系统的能量流的生物化学和细胞生物学中的一个字段。这是能量的一个活跃的生物学研究，包括在活的生物体中转换的研究领域和数以千计的不同的细胞过程，例如细胞呼吸作用和许多其他代谢过程，可导致生产研究和利用能源的形式，如 ATP 分子。

4 Growth, development and metabolism are some of the central phenomena in the study of biological organisms. The role of energy is fundamental to such biological processes. The ability to harness energy from a variety of metabolic pathways is a property of all living organisms. Life is dependent on energy transformations; living organisms survive because of exchange of energy within and without. In a living organism, chemical bonds are broken and made as part of the exchange and transformation of energy. Energy is available for work (such as mechanical work) or for other processes (such as chemical synthesis and anabolic processes in growth), when weak bonds are broken and stronger bonds are made. The production of stronger bonds allows release of usable energy. 生长发育、 新陈代谢是一些中央现象研究的生物有机体。能源的角色是这类生物过程的基础。利用能量从繁多的代谢途径的能力是所有生物的属性。生活是依赖于能量转换;活的有机体生存由于内部和外部的能量的交换。 在一个活的有机体，化学键的破裂和作为交换和能量转换的一部分。能源是可用于 （机械等） 的工作或其他进程 （如化学合成和合成代谢的过程中增长），当弱键已破，都是更强的债券。生产的更强的债券允许可用能量的释放。
