What three structures make up the bacterial cytoskeleton and what are they used for? Which are used in eukaryotic flagella? Which are used in pseudopodia motility?
microtubule structure
Composed of protein tubullin is the largest
intermediate filaments functions
aid in maintaining shape anchor organelles that don't need to move line internal membrane of nucleus
microfilament structure
are polymers of actin smallest cytoskeletal structure
intermediate filament structure
composed from a variety of proteins
microfilament function
important in maintaining or changing cell shape. movement in muscle cells
which is used for pseudopodia motility
microfilaments constructs and deconstructs the microfilament to extend pseudopodia.
which one is eukaryotic flagella made up of
microtubules in a 9 by 2 arrangement surrounded by a plasma membrane
3 structures
microtubules, microfilaments, intermediate filaments
microtubule function
organization of organelles equal distribution of chromosomes during mitosis cell motility both internally and externally (flagella and cilia)
