WebThe Cytoskeleton. The cytoskeleton, as the name implies, is the structural component of the cell and is composed of a network of proteins that are constantly destroyed, renewed, and newly built. The cytoskeleton functions in maintaining the cell shape, resisting deformation, movement both inside (transport of vesicles within) and migratory ... WebCollectively, this network of protein fibers is known as the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( Figure ). Here, we will examine each.

Difference Between Prokaryotic and Eukaryotic Cells

WebProkaryotes do contain vacuoles and a cytoskeleton; the most prominent part of the cytoskeleton being arranged into a structure called the flagellum. The flagellum is a long, whip-like structure that helps the prokaryote move, although the structure is not always present. Other cytoskeleton structures include fimbriae (numerous short appendages ... WebMicrofilaments are the thinnest part of the cytoskeleton, and are made of actin [a highly-conserved protein that is actually the most abundant protein in most eukaryotic cells]. Actin is both flexible and strong, making it a useful protein in cell movement. In the heart, contraction is mediated through an actin-myosin system.
