Rotation in one direction results in a controlled forward motion of the bacterium. Rotation in the other direction makes the bacteria move in a random tumbling fashion.
The resulting bacterial motility combined with the change in direction of rotation produces a kind of random walk that allows cell to cover a lot of ground in a general direction. The base of the flagellum of eukaryotic cells is firmly anchored to the cell membrane and the flagella bend rather than rotate.
Protein chains called dynein are attached to some of the double microtubules arranged around the flagella filaments in radial spokes. The dynein molecules use energy from adenosine triphosphate ATP , an energy storage molecule, to produce bending motion in the flagella. The dynein molecules make the flagella bend by moving the microtubules up and down against each other. They detach one of the phosphate groups from the ATP molecules and use the liberated chemical energy to grab one of the microtubules and move it against the tubule to which they are attached.
By coordinating such bending action, the resulting filament motion can be rotational or back and forth. While bacteria can survive for extended periods in the open air and on solid surfaces, they grow and multiply in fluids. Typical fluid environments are nutrient-rich solutions and the interior of advanced organisms.
Many of these bacteria, such as those in the gut of animals , are beneficial, but they have to be able to find the nutrients they need and avoid dangerous situations. Flagella allow them to move toward food, away from dangerous chemicals and to spread when they multiply.
Not all bacteria in the gut are beneficial. It relies on flagella to move through digestive system mucus and avoid areas that are too acid. When it finds a favorable space, it multiplies and uses flagella to spread out. Studies have shown that the H. Bacteria can be classified according to the number and location of their flagella. Monotrichous bacteria have a single flagellum at one end of the cell. Lophotrichous bacteria have a bunch of several flagella at one end.
Peritrichous bacteria have both lateral flagella and flagella at the ends of the cell while amphitrichous bacteria can have one or several flagella at both ends. Eukaryotic cells with a nucleus and organelles are found in higher plants and animals but also as single-celled organisms.
Eukaryotic flagella are used by primitive cells to move around, but they can be found in advanced animals as well. Miyata, M. Centipede and inchworm models to explain Mycoplasma gliding.

This concentration gradient is generated using energy sources, such as redox potential or ATP. Once established, the proton motive force can be used to carry out work, for example, to synthesize ATP or pump compounds across the membrane.
