Cytoskeleton and microtubules
WebAs their name implies, microtubules are small hollow tubes. The walls of the microtubule are made of polymerized dimers of α-tubulin and β-tubulin, two globular proteins . With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression, provide a track along which vesicles move ... WebApr 8, 2024 · Microtubules are microscopic, hollow tubes made from alpha and beta-tubulin that are a neighborhood of the cell’s cytoskeleton. Microtubules extend throughout the cell providing it with proper shape and keeping the organelles their original place. They are the most important structures within the cytoskeleton and are about 24nm thick.
