Mind map: Cytoskeleton
Map content
Cytoskeleton
- A network of fibers extending throughout the cytoplasm, regulates cellular activities (ex. moving macromolecules).
- Keeps the cell together (structure) and insides components(organelles) in place ("anchor-age")
Motor proteins
- Movement! Converting chemical energy into mechanical work (using ATP or proton pump).
- Different proteins
- Has same job (transportation), But different motor proteins are transport/moving different substrates that are for different jobs.
Vesicles
- travel along "monorail" in cytoskeleton
Fibers of cytoskeleton
- Microtubules
- Thickest
- Function
- Guiding movement, Shaping cell, Separating chromos.in cell division
- Cilia + flagella
- Basal body keeps them attached
- Has dynein (motor protein) to get them moving along!
- Microfilaments
- Thinnest, made of actin (a twisted rope shape motor protein),
- Bear tension, resisting pulling forces inside the cell
- Cortex
- A bunch of microfilaments, inside plasma membrane, gives cell a shape.
- Function
- Motor proteins: Myosin and actin get things moving along
- Muscle cells
- A bunch of microfilaments
- Intermediate filaments
- In-between size, Break it down --> stronger than microtubules
- Function
- Give cell a shape and parks the organelles in a spot.
- More permenant of the 3.
- Microtubules
