Abstract
We present a simple model to study the statistical fluctuations of mem branes containing active proteins. We show that the long-wavelenght li mit of the shape fluctuation spectrum of active membranes diverges wit h a power law which is different from that of membranes in thermal equ ilibrium. This leads to a persistence length for active membranes whic h is much shorter than that of equilibrium membranes.
