BIO 1140 Lecture Notes - Lecture 6: Glycerol, Phospholipid, Tubulin
Document Summary
Microtubule motor proteins that transport cellular cargo towards the + end of the mt are brining components to the cell periphery (i. e. anterograde) This is true - dynein does this. Propose a way the axon portion of a cell can grow to reach a target (i. e. muscle) describe the structural elements involved and steps required. The more motor proteins and vesicles the more you can transport. Tubular and actin to not need to be shuttles. The cell body is far from the axon. Need to transport tubuilin to the end of the axon. Microtubules will start extending when tubulin monomers are added to the end of the microtubule. The adding side should be greater than the losing side. In order to grow must add more subunits. Materials required brought by the - more membrane comes from the phospholipids in the membrane of the vesicle transporting elements. Increase in energy will drive the extension.
