What is the function of bacterial flagella quizlet?
The overall function of bacterial flagella is: to keep bacteria in an optimum environment via taxis. A single flagellum, usually at one pole. A single flagellum at both ends of the organism.
What is the function of bacterial flagella?
Flagellum is primarily a motility organelle that enables movement and chemotaxis. Bacteria can have one flagellum or several, and they can be either polar (one or several flagella at one spot) or peritrichous (several flagella all over the bacterium).
What is flagella quizlet?
STUDY. Flagella. Structures that allow for motility in some organisms.
What is the function of the flagellum quizlet?
What are flagella and what is their structure? Responsible for motility and movement. Composed of filament, hook, and basal body.
How are bacterial flagella attached to the body?
Bacterial flagella are helically shaped structures containing the protein flagellin. The base of the flagellum (the hook) near the cell surface is attached to the basal body enclosed in the cell envelope. The flagellum rotates in a clockwise or counterclockwise direction, in a motion similar to that of a propeller.
What is the function of flagella and cilia quizlet?
Function: Cilia and flagella move small particles past fixed cells and are major form of locomotion in some cells.
What is the relationship between the presence of flagella and bacterial pathogenicity?
Flagella contribute to virulence of pathogenic bacteria through chemotaxis, adhesion to and invasion of host surfaces.
How do bacterial flagella differ from eukaryotic flagella?
Eukaryotic flagella are microtubule-based structures, which are attached to the cell at the cell membrane through basal bodies while prokaryotic flagella are located outside of the plasma membrane.
What are the three parts of bacterial flagella quizlet?
Terms in this set (45)

What cell would have a flagellum quizlet?
Flagella are only found in Gram-negative bacteria. A Gram-positive flagellum does not have a membrane covering its filament; A Gram-negative flagellum does. A Gram-positive flagellum has only two rings in its basal body; Gram-negatives each have four.
What is the relationship between the presence of flagella and bacterial chemotaxis?
Chemical information received at membrane-receptors influence the rotation of the flagellum motor, thus enabling the bacteria to respond to changes in the external environment by ordered motility. This signal transduction happens through the chemotaxis system (reviewed by Kojima and Blair [4]).
