Question

Bacterial flagella are made up of ______.

• A. proteins
• B. amines
• C. lipids
• D. carbohydrates

Answer 1

The correct option is A

proteins

A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and Eukaryota, also known as protists, plants, animals, and fungi. While all three types of flagella are used for locomotion, they are structurally very different. Bacterial flagella are made up of a protein called as flagellin. Flagellin is a protein that arranges itself in a hollow cylinder to form the filament in a bacterial flagellum.
