The chemokinetic and chemotactic behavior of Rhodobacter sphaeroides: two independent responses
Explore this paper's citation graph
Summary
The results presented here show that the chemokinetic response is separate from the chemotactic response, although some compounds can induce both responses, and metabolism is required for chemotaxis but not chemokinesis, and a reduction in chemoattractant concentration may cause the major Chemotactic signal.
