BIOL 266 DETAILED FINAL NOTES| CONCORDIA UNIVERSITY|UPDATED 2024/2025 UNIT 9.0 – THE CYTOSKELETON Two functions of the cytoskeleton: 1. Provides structural framework for the cell,serving as a scaffold that determines cell shape and the general organisation of the cytoplasm. 2. Responsible for the movements of the entire cells and for the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm. The cytoskeleton is composed of 3 principa...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments: made of actin; determines the shape of cell surface and is important for the movement of the cell Microtubules: made of alpha and beta dimers ; act as tracks for vesicles and other properties to move about the cell with motor proteins Intermediate filaments: made of various proteins + rope-like fibers; provide mechanical strength The actin filament and microtubules carry stuff by "w...
