Cellular motions and thermal fluctuations: the Brownian ratchet

C. S. Peskin, G. M. Odell, G. F. Oster

Research output: Contribution to journalArticlepeer-review


We present here a model for how chemical reactions generate protrusive forces by rectifying Brownian motion. This sort of energy transduction drives a number of intracellular processes, including filopodial protrusion, propulsion of the bacterium Listeria, and protein translocation.
