Definition

Meaning and Definition

Increased random movement of a cell or organism in response to a chemical stimulus, without directional orientation towards or away from the stimulus source.

In biology, a non-directional change in the speed or frequency of movement in response to a chemical concentration gradient, distinct from chemotaxis (directional movement).

FAQ

Frequently Asked Questions

Chemotaxis is directional movement toward or away from a chemical stimulus. Chemokinesis is a non-directional change in the speed or turning rate of movement in response to a chemical, without orientation to the gradient.

It is almost exclusively used in microbiology, immunology, parasitology, and cell biology when describing the movement behaviour of cells like bacteria, leukocytes, or protozoa.

Yes, though rare. Forms like 'chemokinese' or 'chemokinesize' are technically possible in scientific writing, but the noun form is far more common.

No. It is a highly specialised scientific term with near-zero frequency in everyday, business, or general academic English outside the life sciences.

Increased random movement of a cell or organism in response to a chemical stimulus, without directional orientation towards or away from the stimulus source.

Chemokinesis is usually highly technical in register.

Chemokinesis: in British English it is pronounced /ˌkiːməʊkɪˈniːsɪs/, and in American English it is pronounced /ˌkimoʊkɪˈnisɪs/. Tap the audio buttons above to hear it.
