Many cytoskeletal biopolymers are "active," consuming energy in largequantities. In this Letter, we identify a fundamental difference between activepolymers and passive, equilibrium polymers: for equal mean lengths, activepolymers can reorganize faster than equilibrium polymers. We show thatequilibrium polymers are intrinsically limited to linear scaling between meanlifetime and mean length, MFPT ~ <L>, by analogy to 1-d Potts models. Bycontrast, we present a simple active-polymer model that improves upon thisscaling, such that MFPT ~ <L>^{1/2}. Since to be biologically useful,structural biopolymers must typically be many monomers long, yet responddynamically to the needs of the cell, the difference in reorganization kineticsmay help to justify active polymers' greater energy cost.
