摘要
介绍了化学热力学基础和葡萄糖体内氧化的3个阶段。葡萄糖体内外氧化符合化学热力学原理中的盖斯定律;酶参与和ATP的引入提高了反应活化分子数,实现了常温常压下的葡萄糖体内氧化;葡萄糖体内氧化的多步骤有助于获得最大非体积功,且多步反应可以有效调控能量在体内的释放速度;葡萄糖体内氧化的前2个阶段证明了葡萄糖可以适应不同条件为生物体提供能量,且不同阶段的中间产物也在生命活动起着重要作用。通过延伸讨论揭示了ATP在葡萄糖体内氧化的三重作用,作为能量形式提高反应活化分子数和存储能量,同时ATP还具有催化剂的特点。
The basis of chemical thermodynamics and three oxidation stages of glucose in vivo are first introduced briefly. Then the thermochemical principles of in vivo oxidation of glucose was revealed. The in vivo and in vitro oxidation of glucose conforms to Hess’ Law. The action of enzyme and the energy of ATP increase the number of activated molecules to achieve the in vivo oxidation of glucose at ambient temperature and pressure. The multi-step oxidation of glucose in vivo is helpful to obtain the maximum power, while the multi-step procedure can effectively regulate the release rate of energy in vivo. The first two stages of glucose oxidation in vivo demonstrate that glucose can be adapted to different conditions to provide energy for organisms. The intermediates of different stages also play an important role in life activities. The triple-action of ATP in the in vivo oxidation of glucose is revealed through an extended discussion. ATP is an energy form to increase the number of activated molecules and for energy storage. Moreover, ATP has the characteristics of a catalyst.
