The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. It is a subset of the endomembrane system of the endoplasmic reticulum. 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 ...
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. The smooth endoplasmic reticulum differs from the rough endoplasmic reticulum (RER) by its lack of ribosomes.
Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell. The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
Smooth endoplasmic reticulum is a part of the endoplasmic reticulum that is tubular and lacks ribosomes. It is associated with lipid synthesis, carbohydrate metabolism, calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.
The smooth Endoplasmic Reticulum (SER) is a cell organelle found in all eukaryotic cells, including plants and animals. It is a mesh-like network of membranes whose basic function is to help produce and distribute cellular products like proteins, lipids, and other molecules throughout the cell.
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.
The smooth endoplasmic reticulum is the primary location for lipid synthesis. As such, it does not contain any ribosomes. Rather, it conducts a series of reactions which create the phospholipid molecules necessary to create various membranes and organelles.
The Smooth endoplasmic reticulum consists of the enzyme glucose-6-phosphatase. It converts glucose-6-phosphate to glucose. In the sebaceous gland, there is the presence of plenty of smooth endoplasmic reticulum. It is also found in leucocytes. It is also believed that the sphaerosomes are originated from the smooth endoplasmic reticulum.
The smooth endoplasmic reticulum is a region of the endoplasmic reticulum composed of tubular elements lacking ribosomes and associated with many metabolic processes, including carbohydrate metabolism, the synthesis of lipids, cholesterol, and carbohydrates, and drug metabolism (Dorland, 2011).
What is Smooth Endoplasmic Reticulum? The smooth endoplasmic reticulum (smooth ER) is a type of organelle found in both animal and plant cells. It is part of the larger endoplasmic reticulum network, which also includes the rough endoplasmic reticulum.
