摘要：

We study the transverse diffusion of a tagged membrane point in membranes that include active sites, such as ion pumps. At very short times we find a subdiffusive behavior [r(2)] similar to t(2/3) as for passive membranes. At long times we iind a few regimes which show a strongly enhanced diffusion, [r(2)] similar to t(alpha) with 1 < alpha < 2. One of the regimes shows a purely ballistic motion alpha = 2.
