| Abstract: | 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,the 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 relat... |
