Flagella and Motility

The term Archaellum refers to the

• Motility pattern of Archaea

• Flagella of Archaea

• Sub units of Archaeal flagella

• Difference between the bacterial and archaeal flagellum

Flagella functions by converting

• mechanical energy to chemical energy

• chemical energy to mechanical energy

• mechanical energy to potential energy

• metabolic energy to chemical energy

• L > P > MS > C (Gram negative)
• P > MS > C (Gram positive)
• both
• L > P > MS > C (Gram positive)
