Study Notes
- The cytoskeleton supports the cell membrane and contributes to the cell's organization and dynamics.
- It has active mechanical forces such as polymerization, tension, and contraction.
- It participates in cell movement, division, and morphology.
- The cytoskeleton is responsible for mitosis and cell division.
- It is made up of polymers of polypeptides with non-covalent bonds.
- The majority of the dynamics occur at the ends of filaments.
- There are three types of filaments: microfilaments, microtubules, and intermediate filaments.
- Microfilaments are made of actin and are approximately 8nm.
- Microtubules are made of tubulin and are approximately 25nm.
- Intermediate filaments are approximately 10nm.
