Cytoskeleton three parts
WebIn eukaryotes, there are three types of protein fibers in the cytoskeleton: microfilaments, intermediate filaments, and microtubules. Here, we'll examine each type of filament, as well as some specialized structures … WebThe endoplasmic reticulum. The endoplasmic reticulum ( ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs. The discs and tubules of the ER are hollow, and the space inside is called the lumen.

There are three major types of filaments that make up the … WebThe cytoskeleton helps the cell move in its environment and controls the movement of all of the cell's interior workings. Microfilaments are the smallest of the three parts of the cytoskeleton, as they are only around seven nanometers in diameter. These helically shaped filaments are made up of G-actin proteins.

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.
