MCQ IN MEDICINE

Detailed explanation-1: -Bacterial motility is typically provided by structures known as flagella. The bacterial flagellum differs in composition, structure, and function from the eukaryotic flagellum, which operates as a flexible whip-like tail utilizing microtubules.

Detailed explanation-2: -The bacterial flagellar motor is powered by the transmembrane electrochemical gradient of ions, namely ion motive force (IMF) and rotates the flagellar filament to generate thrust to propel the cell body. The maximum motor speed reaches 300 revolutions per second in E.

Detailed explanation-3: -A flagellum (/fləˈdʒɛləm/; PL flagella) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility.

Detailed explanation-4: -The bacterial flagellum is a complex apparatus assembled of more than 20 different proteins. The flagellar basal body traverses the cell wall, whereas the curved hook connects the basal body to the whip-like flagellar filament that protrudes several µm from the bacterial cell.

Detailed explanation-5: -OK-let’s talk about this thing known as a flagellum (if there are more than one, together they are called, flagella-the plural form of flagellum). The word “flagellum” is Latin for whip. This structure is present as an appendage on certain bacteria and allows the bacteria to move around.
