Is walking on a treadmill good exercise for losing weight? I have changed my diet. I eat ALOT of salads and fish and chicken and I walk for 30 to 60 minutes on a treadmill several times a week. I have lost 5 pounds in about a week, but kind of stopped losing weight or at least have not noticed it as much. I also eat alot of fresh fruit. I was wondering if what i am doing is a good way to lose weight.
Many bacteria are motile and use flagella to swim through liquid environments. 2. The basal body of a bacterial flagellum functions as a rotary molecular motor, enabling the flagellum to rotate and propel the bacterium through the surrounding fluid. 3. Bacterial flagella appear in several arrangements, each unique to a particular organism.
Flagella are helical shaped structure which is composed of subunits of a protein called flagellin. The wider region at the base of the flagellum is called hook. It is different in structure than that of the filament. Hook connects filament to the motor portion of the flagellum called basal body.any prokaryotes are motile, and the majority of motile prokaryotes moves by means of flagella. Medical Importance of Flagella. 1  Role in Pathogenesis: Escherichia coli and proteus spp are common causes of Urinary tract infections.
