Smooth Endoplasmic Reticulum Function In Animal Cell
Camila Farah
The smooth endoplasmic reticulum has a tubular form.
The smooth endoplasmic reticulum on the other hand does not have ribosomes. Other functions of the smooth endoplasmic reticulum depend on the cell type. The endoplasmic reticulum er is an important organelle in eukaryotic cells. A cell s endoplasmic reticulum er contains a network of tubules and flattened sacs.
Smooth endoplasmic reticulum structure. The er performs multiple functions in both plant and animal cells. Cells need the rough and the smooth. Smooth endoplasmic reticulum meshwork of fine tubular membrane vesicles part of a continuous membrane organelle in the cytoplasm of eukaryotic cells that is involved in lipid synthesis.
Its main functions are the synthesis of lipids steroid hormones the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The endoplasmic reticulum er is in essence the transportation system of the eukaryotic cell and has many other important functions such as protein folding it is a type of organelle made up of two subunits rough endoplasmic reticulum rer and smooth endoplasmic reticulum ser the endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened. Smooth endoplasmic reticulum and rough endoplasmic reticulum. It participates in the production of phospholipids the chief lipids in cell membranes and are essential in the process of metabolism.

The er can be classified in two functionally distinct forms. The er produces transmembrane proteins and lipids for its membrane and for many other cell components including lysosomes secretory vesicles the golgi appatatus the cell membrane and plant cell vacuoles. It plays a major role in the production processing and transport of proteins and lipids. In a muscle cell for example it is responsible for releasing calcium ions when it receives a signal that the muscle cell must contract.
This function of the smooth endoplasmic reticulum is so specialized in muscle cells that the organelle has a different name. This statement certainly applies to the endoplasmic reticulum an organelle found in eukaryotic cells. The endoplasmic reticulum er is an extensive system of interconnected tubules and cisternae flattened sac like structures that can be found in almost all eukaryotic cells except the red blood cells of mammals. Endoplasmic reticulum has two major regions.
The smooth endoplasmic reticulum smooth er is a membranous organelle found in most eukaryotic cells. Smooth endoplasmic reticulum ser and rough endoplasmic reticulum rer. The smooth endoplasmic reticulum differs from the rough endoplasmic reticulum rer by its lack of ribosomes. Smooth endoplasmic reticulum definition.
