Document Summary
The inside of the cell is a well organized scaffold of protein structures that carry out more than just a skeletal function for the cell. Besides its structural role, name at least 2 other functions that the cytoskeleton achieves in a typical cell: Functions include: provide structure and support, intracellular transport. Responsible for transport system required for the eukaryotic cell organization: position organelles within the cell. And transport the organelles to their position: generate force for cell movement. Sperm, needs to move using a fast moving flagellum. Lots of atp needed to create a fast and efficient motion of flagella. Atp comes from mitochondria: contribute to cell division. Mitosis; lines up chromosomes on metaphase plate (microtubules) Also pulls the chromosome apart during anaphase. Involved in a lot of different steps in the cell. Given the cytoskeleton"s different roles, what is an important property of these structures remember, we said this was a 3d, dynamic network.
