Document Summary
Microbiology notes: week 3: cell structures and their functions: Made up of several different types of molecules, There is eukaryotic flagella but they are not the same as bacterial. Flagella are embedded in the cytoplasmic membrane, Ring proteins embedded in the flagella within the cytoplasmic membrane, Mot proteins are associated with the ring protein, Mot proteins use proton motive force to make it rotate, 1000 + proton for each rotation, over 40 genes are required for formation and function, Other ring proteins are involved with the stabilization of the flagellum within the cell wall and membrane, The p ring is associated within the peptidoglycan, L ring associated with the outer membrane and the lipopolysaccharide, The hook protein connects the filament to the rest of the structure, The filament is the part of the flagellum on the outside of the bacteria, Flagella can rotate fast enough to propel the bacteria at relatively high speeds,
