Complete details of the thermodynamics and molecular mechanisms of ATP synthesis/hydrolysis and muscle contraction are offered from the standpoint of the torsional mechanism of energy transduction and ATP synthesis and the rotation-uncoiling-tilt (RUT) energy storage mechanism of muscle contraction. The manifold fundamental consequences and mechanistic implications of the unified theory for oxidative phosphorylation and muscle contraction are explained. The consistency of current mechanisms of ATP synthesis and muscle contraction with experiment is assessed, and the novel insights of the unified theory are shown to take us beyond the binding change mechanism, the chemiosmotic theory and the lever arm model. It is shown from first principles how previous theories of ATP synthesis and muscle contraction violate both the first and second laws of thermodynamics, necessitating their revision. It is concluded that the new paradigm, ten years after making its first appearance, is now perfectly poised to replace the older theories. Finally, applications of the unified theory in cell life and cell death are outlined and prospects for future research are explored. While it is impossible to cover each and every specific aspect of the above, an attempt has been made here to address all the pertinent details and what is presented should be sufficient to convince the reader of the novelty, originality, breakthrough nature and power of the unified theory, its manifold fundamental consequences and mechanistic implications, and its applications in health and disease.
提供了从能量转导的扭转机制和肌肉收缩的旋转-展开-倾斜(RUT)能量储存机制的角度来看,ATP 合成/水解和肌肉收缩的热力学和分子机制的完整详细信息。解释了统一的氧化磷酸化和肌肉收缩理论的多方面基本后果和机械学意义。评估了当前 ATP 合成和肌肉收缩机制与实验的一致性,并表明统一理论的新见解使我们超越了结合变化机制、化学渗透理论和杠杆臂模型。从第一性原理出发,说明了以前的 ATP 合成和肌肉收缩理论如何违反热力学第一定律和第二定律,需要对其进行修正。得出的结论是,在首次出现十年后,新范式现在完全可以取代旧理论。最后,概述了统一理论在细胞生命和细胞死亡中的应用,并探讨了未来研究的前景。虽然不可能涵盖上述每个特定方面,但这里试图解决所有相关细节,并且所呈现的内容应该足以使读者相信统一理论的新颖性、原创性、突破性和力量、其多方面的基本后果和机械学意义,以及它在健康和疾病中的应用。
