Chemo-taxis in bacteria is the movement of these microorganisms toward or away from chemical stimuli in their environment. Bacteria detect chemical gradients through specialized receptors on their surface, which bind to specific attractants or repellents. This binding triggers a signaling cascade that alters the rotation of flagella, allowing bacteria to swim toward favorable environments (attractants) or away from harmful substances (repellents). The process is typically characterized by a series of runs and tumbles, where longer runs indicate movement toward attractants and more frequent tumbles indicate a change in direction.

How do bacteria carry out Chemotaxis?
Bacteria carry out chemotaxis by sensing chemical gradients in their environment using specialized receptors on their cell surface. When these receptors detect attractants or repellents, they trigger a signaling cascade that alters the rotational direction of the flagella, allowing the bacteria to move toward favorable conditions or away from harmful substances. This movement is typically characterized by a series of "runs" (straight movement) and "tumbles" (random changes in direction) that help the bacteria navigate through their surroundings. Overall, chemotaxis enables bacteria to effectively locate nutrients and avoid toxins.
What is the term used to describe white blood cells migrating toward bacteria?
CHEMOTAXIS final answer by Willie Jun R. Broce, BSED,RN, MAED
Movement of a cell toward a chemical stimulus is termed?
positive chemotaxis
What is the attraction of leukocytes?
Chemotaxis
What type of taxis is a bacterial cell exhibiting when it moves toward glucose in the environment?
Chemotaxis - this is the general term for bacterial motility when sensing a compound in the environment. If moving toward it is called positive chemotaxis, if away from it is negative chemotaxis.
What is the role of the flagella in a bacteria cell?
The role of a flagella in a bacterial cell is motility. Through the back and forth movements of the flagella bacteria can propel themselves through their environment. The flagella also help bacteria undergo chemotaxis, the ability to move away from some stimuli and move towards others.
How do one celled organisms act?
One-celled organisms, like bacteria and protozoa, exhibit various behaviors such as moving towards a food source (positive chemotaxis) or away from harmful substances (negative chemotaxis), responding to light (phototaxis), and reproducing through binary fission or budding. They may also form biofilms for protection and cooperation.
Is the final step of phagocyte mobilization?
Chemotaxis
Cellular migration directed by a chemical gradient?
chemotaxis
Which of the following is the correct sequence of events in phagocytosis?
chemotaxis, adherence, ingestion, digestion, killing
How do bacteria respond to their surroundings?
Bacteria respond to their surroundings through various mechanisms, including chemotaxis (movement toward or away from chemical stimuli), detecting and responding to changes in temperature, pH, and nutrient availability, and forming biofilms to protect themselves from adverse conditions or antimicrobial agents. These responses allow bacteria to adapt to different environments and ensure their survival and growth.
