Strucuture bacterial flagella pili 1

This illustration represents the cross-sectional structure of an axoneme, a core component of cilia and flagella. The axoneme consists of microtubules arranged in a specific geometric pattern, which primarily includes nine pairs of microtubules surrounding two central single microtubules. The depiction includes colors such as gray, orange, blue, and red, likely to represent different components or protein subunits within the structure. The central part of the axoneme is where the coordination for motility and stability occurs, facilitated by motor proteins interacting with the microtubules. This structure is integral for cell motility and intracellular transport.
