Introduction to Prokaryotic Flagella
Multiple Choice
Which of the following correctly identifies the structure that anchors a typical Gram-negative prokaryotic flagellum to the cell wall and membrane?
A
Hook
B
Basal body
C
Filament
D
Capsule
검증된 단계별 안내1
Understand the components of a typical Gram-negative bacterial flagellum: the filament, hook, and basal body.
Recall that the filament is the long, whip-like structure responsible for motility but does not anchor the flagellum.
Recognize that the hook connects the filament to the basal body and acts as a flexible coupling, but it is not the anchoring structure itself.
Identify the basal body as the complex structure embedded in the cell envelope, which anchors the flagellum to the cell wall and membrane.
Note that the capsule is an external polysaccharide layer unrelated to flagellar anchoring.
