Document Summary
Microtubules are structural components of cilia and flagellum. The whole thing is surrounded by a cell membrane. Cilium pushes one way, recovers, and pushes back again. Organelles attach to the microtubules, and move along the tubule. Also, one motor molecule can use atp to grasp onto the microtubule and move along. 9 pairs of microtubules, and in the center, there is another pair. In the middle, there is a specialized arrangement of microtubules (middle is a central microtubule) Also radial anchor proteins, and motor proteins travel down the length of the cilia (called dinine) In the bottom (anchor), the arrangement is different. Instead of pairs, there are triplets, (they span out) Single cells move along by streaming cytoplasm out. Goes from one state to another, to polymerize and depolymerize. Three types of junctions between animal cells. They form a belt around the cells to allow for them to stick closely together.
