Bacterial flagella (IMAGE) Nagoya University Caption Bacterial flagella are generated from the cell surface (A). Motors are buried within the cell membrane at the bases of flagellar filaments (indicated by white arrows). The motor part is shown by the cross-section of three-dimensional tomogram images using cryo-electron microscopy (B). The white-dashed line in (B) is enlarged in (C). The densities of the C-ring and the transport apparatus (EXP and ATPase) are easily observed.
