Muscle contraction time scale

Motor molecules play a key role in muscular contraction, ceU division, and cell transport. Molecular motors are microscopic systems that move along one-dimensional periodic structures. They undergo several states, within each of which operates at local equilibrium on timescales small compared to the exchange rates between these states. For example, for the transient response of muscles, the fastest characteristic times of the motors are in the range of miliseconds. Thermal equilibrium occurs on length scales of around 10 nm after around 10 to 100 nanoseconds. The states of the proteins during muscular contraction therefore had to be in local equilibrium. Up to five or six different states could be involved (Julicher et al., 1997). [Pg.698]
