Document Summary
Check slide 3 lecture 7 for more reference. Intermediate filaments add strength, anchor filaments or actin and myosin. *great for m/c properties of cytoskeletal filaments ex. Two intertwined composition protein tubulin proteins including strands desmin, keratin, lamin, composed of the. Cell motility (cilia & flagella) protein actin in lecture 7. Know the nanometer (25nm outside, 15nm inside) Microtubules form the structural supports for cilia(plural) and flagella (singular) Flagella/cilia a circle of 9 double microtubules. Motor proteins move vesicles and chromosomes along microtubule tracks. Watch the inner life of a cell link on the slides. Thinnest class of cytoskeletal fibres 7nm diameter. Solid rods composed of globular protein subunits called actin consists of a twisted double chain of actin subunits. Dynamic structure change length by addition and loss of actin. Other cells wide bands of actin filaments. Occur singly in parallel bundles, and in interlinked networks. Provide structural support in many cells and tissues.
