The endoplasmic reticulum granular (ER granular) is one of three main structures that form the endoplasmic reticulum (ER) - a membrane-bound system in the cytoplasm of the cell that performs many functions. The granular ER is one of the most common and important structures of the ER, and its functions are also diverse.
The endoplasmic reticulum is a complex system of membrane structures associated with the cytoplasmic membrane of the cell. It consists of individual cisternae, tubes and sacs that form a network and allow the cell to move materials such as proteins, lipids and carbohydrates between different parts of the cytoplasm.
EPS granular, also known as granular endoplasmic reticulum, is one of the three main types of EPS. It differs from other types in its structure, which includes many small and round granules called ribosomes. These granules are composed of ribonucleoproteins, which are large proteins containing RNA. They play an important role in protein synthesis, as well as in the regulation of cell metabolism.
One of the main functions of granular ER is protein synthesis. Ribosomes on granules synthesize proteins on an RNA template, which they receive from the cell nucleus. Proteins synthesized in the granular ER can be sent to other parts of the cell for use or storage.
Granular EPS also plays a role in cell metabolism. It is involved in the metabolism of lipids and carbohydrates, as well as other metabolic processes, such as the regulation of the levels of hormones and other substances in the cell.
In addition, granular ER may play a role in protecting cells from toxic substances. It can capture and remove toxins from the cell or protect it from their effects.
Thus, granular ER is an important structure of the endoplasmic reticulum, which plays a key role in the synthesis and metabolism of proteins, as well as cell protection.
The endoplasmic reticulum is a membrane organelle whose main function is the synthesis of fats, carbohydrates, vitamins, hormones, hemoglobin, bilirubin, enzymes and other compounds. Steroid hormones are synthesized here and IgA is synthesized. Granular type of ER - is a type of ER that is oval in shape and large in size, containing many small amorphous bodies arranged in the form of loops or clusters. Large folds can form tubes that are spherocytic in shape. In these tubes many biologically active substances are directly synthesized and germ cells are formed. The size of individual loops is about 3 microns. Thus,
