Prokaryotic flagella are made of a protein called _________________.
Verified step by step guidance1
Understand that prokaryotic flagella are structures used for motility in bacteria.
Recall that flagella are composed of protein subunits that polymerize to form the filament.
Identify the specific protein that makes up the filament of prokaryotic flagella.
Recognize that this protein is called flagellin, which assembles into a helical filament.
Conclude that the answer to the question is the protein 'flagellin'.

1mKey Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Prokaryotic Flagella Structure
Prokaryotic flagella are long, whip-like appendages that enable bacterial motility. They are composed of a filament, hook, and basal body, each playing a role in movement and attachment.

Prokaryotic Flagellar Structure
Flagellin Protein
Flagellin is the primary protein that makes up the filament of prokaryotic flagella. It polymerizes to form a helical structure, which rotates to propel the bacterium through its environment.

Function of Flagella in Prokaryotes
Flagella allow bacteria to move toward favorable conditions or away from harmful stimuli, a behavior known as chemotaxis. This motility is crucial for survival and colonization.
