Microtubules Flashcards
Where are microtubules found?
Found throughout the cytoplasm of eukaryotic cells
In what specific places are microtubules particularly important?
Around the nucleus, in the mitotic spindle, etc.
What is the shape and structure of microtubules?
They are rigid, hollow rods or tubes approximately 25 nm in diameter.
What protein composes microtubules?
A single type of globular protein called tubulin.
What role do microtubules play in determining cell shape?
They act as a compressive force to determine cell shape.
How do microtubules support the cell?
They provide mechanical and structural support.
How do microtubules assist in material transport?
They act as tracks for motor proteins to transport vesicles, organelles, and other materials.
What role do microtubules play in mitosis?
They form spindle fibers to help separate chromosomes.
What dynamic behavior do microtubules exhibit?
They undergo continual assembly and disassembly within the cell.
