BIOL 1000 Lecture Notes - Lecture 1: Melanosome, Nuclear Lamina, Depolymerization
Document Summary
Microfilaments (constantly changing) apart: depolymerization tubes being removed from the plus end (taking things shaped, do not come from the centrosome. Atp requires the exchange of adp for atp not adding a phosphate adp is taken off and atp is put in stuck bound. Dynein"s: walking towards centrosome minus end, they walk like kinesin, involve in the transport and whole cell movement, movement of flagella and cilia, only way to not be bound is to hydrolyze. Flagella and cilia: movement of flagella is different than we see in bacteria (circular motion) in eukaryotes there is wave like motion, cilia is also wave motion, same functions (moving the cell along) but different waves. Microfilaments: create a spiral, minus and plus end not related to centrosome, motor protein mysein walk towards the plus end of the actin, sarcoplasmic (sarco=muscle) holds calcium which is essential to muscle. Anchoring junction: between the cytoskeleton and outer membrane. Cell junctions (animal: ex; heart muscle, skin.
