Detailed explanation-1: -The flagellar motors of E. coli and Salmonella rotate in both counterclockwise (CCW) and clockwise (CW) without changing the direction of ion flow. E. coli and Salmonella cells can swim in a straight line by bundling left-handed helical filaments behind the cell body (run) when all of them rotate in CCW direction.
Detailed explanation-2: -Flagella are filamentous protein structures found in bacteria, archaea, and eukaryotes, though they are most commonly found in bacteria. They are typically used to propel a cell through liquid (i.e. bacteria and sperm). However, flagella have many other specialized functions.
Detailed explanation-3: -Flagella propel bacteria through the body The rotation of the filament allows bacteria to move around in their environment. The motor embedded in the bacterial cell membrane rotates-just as a car motor spins beneath the hood of the vehicle-to drive the movement of the filament outside.
