Most . possess one or more flagella on their surface that allow them to swim. . The cytoskeleton is a network of protein fibers within a cell, that crisscross the cytoplasm of all eukaryotic cells. The cytoskeleton is a very dynamic system that is constantly assembling and . dissembling. . The . cytoskeleton . is a network of fibers extending throughout the cytoplasm. It organizes the cell. ’s structures and activities, anchoring many organelles. © 2014 Pearson Education, Inc.. Video: Organelle Transport. By: Tim Yacoub and Lizette Magdaleno . Cytoskeleton Overview. Cytoskeleton is a “network of fibers that extend[s] throughout the cytoplasm,”(113). . It’s three structures: microtubules, microfilaments, and intermediate filaments. :. contain enzymes that transfer . hydrogen. from various substrates to . oxygen. .. Functions of peroxisomes:. Hydrogen peroxide . (H. 2. O. 2. ) is a poison, but the peroxisome has enzyme that converts H. Organelles that Store, Clean up, and Support Organelles that store, clean up, and support Vacuoles, Vesicles, Lysosomes , and the Cytoskeleton Vacuoles are large saclike structures that store materials like :. contain enzymes that transfer . hydrogen. from various substrates to . oxygen. .. Functions of peroxisomes:. Hydrogen peroxide . (H. 2. O. 2. ) is a poison, but the peroxisome has enzyme that converts H. Unit 1: Cells and Proteins. Advanced Higher Biology. Miss Aitken. Structure and Function of the Cytoskeleton. The cytoskeleton is a network of fibres made from protein. It extends the whole way through the cytoplasm.. is a network of fibers composed of . proteins. contained within a . cell. 's . cytoplasm. . The cytoskeletal systems of different organisms are composed by . similar proteins. .. However, structure, function and dynamic behavior of the cytoskeleton can be very different, depending on .
