Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Endoflagella are found in ____
A
spirochetes
B
bacilli bacteria
C
coccobacilli bacteria
D
vibrio bachteria
Explanation: 

Detailed explanation-1: -Spirochetes can be distinguished from other flagellated bacteria by their long, thin, spiral (or wavy) cell bodies and endoflagella that reside within the periplasmic space, designated as periplasmic flagella (PFs).

Detailed explanation-2: -Spirochetes are unique bacteria, exhibiting singular morphological and physiological features. Spirochetal motility relies on endoflagella, which harbor a hook and filament confined within the periplasm, between the inner and outer cell membrane.

Detailed explanation-3: -Endoflagella (axial filaments) are the flagella-like organelles in the periplasmic space encased by the outer membrane. The endoflagella begin at each end of the organism and wind around it, extending to and overlapping at the midpoint.

Detailed explanation-4: -2. Where is the endoflagella located in Spirochetes? Explanation: In spirochetes, the endoflagella or as it is called periplasmic flagella is located between the outer membrane and the protoplasmic cylinder; thus they are located in the periplasmic space of the cell.

Detailed explanation-5: -Spirochetes have a specialized flagella called an endoflagella. These unique flagella form an axial filament. Axial filaments help the spirochete move through rotation of the endoflagella which causes the axial filament to rotate around the body cell and gives the spirochete a twisting motion.
