What is chemotaxis?
Quick Answer
Chemotaxis is movement in response to chemical signals. Bacteria use it to move toward nutrients or away from harmful substances.
The Full Story
Chemotaxis is the directed movement of a cell or organism in response to chemical gradients. Many bacteria can detect nutrients, toxins, oxygen, or other signals and adjust their swimming accordingly. This behavior is crucial for survival because it helps bacteria locate food and suitable habitats. The molecular machinery behind chemotaxis is one of the classic success stories of bacterial cell biology.
Key Facts
1.Movement is guided by chemical gradients
2.Helps bacteria find nutrients and avoid toxins
3.Well studied in model bacteria like Escherichia coli
