How many components of bacterial flagella have?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 3.
-
Filament: This is the long, whip-like part of the flagellum, made up of a protein called flagellin. The filament extends from the surface of the bacterium and is responsible for the actual movement.
-
Hook: The hook connects the filament to the basal body. It is a curved structure that allows the filament to rotate freely, facilitating the flagellum's movement.
-
Basal Body: This part anchors the flagellum to the cell membrane and wall. The basal body consists of several rings.
