What Structure is Responsible for Motility in Spirochetes

Question

What structure is responsible for motility in spirochetes?
A) Axiles
B) Periplasmic flagella
C) Flexible cell wall
D) Compressed nucleus

Accepted Answer

Spirochetes have a unique form of motility called endoflagella, which are also known as periplasmic flagella. These flagella are located in the periplasmic space between the cell wall and cell membrane and form axial fibrils that wrap around the cell body in a helical pattern, allowing for the characteristic corkscrew-like movement of spirochetes.
