chemokinesis


Show Summary Details

Quick Reference

A response to a soluble chemical that involves a change in the motile behaviour of a cell. A change in speed is a positive or negative orthokinesis, a change in the frequency or magnitude of turning behaviour is a klinokinesis. In the extreme case of a strong negative orthokinesis, cells can become trapped because their speed drops to zero, and they accumulate at the top of a gradient of chemokinetic factor, although there is no directional response by individual cells.
