Flagellum function in cell
WebBacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. WebThe flagellum comprises of the principal piece of the spermatozoa and inside it is the fibrous sheath ‑ a characteristic feature of mammalian spermatozoa. 17 Similarly, energy production
