摘要
目的基于肌肉的特殊结构,给出肌球蛋白工作循环的四态模型,研究肌肉中力与位移的关系。方法利用化学动力学方法及其非平衡稳态解,从物理学的角度讨论肌肉中力与位移的关系。结果力与位移的关系与实验结果基本吻合。结论此模型可用于讨论肌肉的力与位移的关系,而且化学动力学方法适用于研究本文体系。
Aim A mechanochemical actin-activated myosin ATPase cycle four-state model has been proposed on the basis of the knowledge of special structure of muscle. Methods From the view of physics, lhe relationship between the average force on the binding states and the displacement of the thick filament was discussed with the chemical kinetic method and the non-equilibrium steady solution of equations. Results The theoretical results are consistent with that of experiment. Conclusion The model is fit to study the relationship between the average force on the binding states and the dis- placement of the thick filament and the chemical kinetic method is also fit to study the system in this article.
