The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most Its main functions are the synthesis of lipids, steroid hormones, the.
Smooth ER Definition, Functions & Structure Video & Lesson Transcript
Some Ca2+-ion mediated ATPase enzymes also direct the interaction of ER. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like.
Rough ER (RER) is involved in some protein production, protein folding. Large amounts of smooth ER are found in liver cells where one of its main functions.
The space inside of the ER is called the lumen.
The Structure and Function of the Endoplasmic Reticulum
Nascent peptides reach the ER via the translocona membrane-embedded multiprotein complex. The other region is called smooth ER because it lacks attached ribosomes.

Each factory makes and distributes the type of product that makes sense for its location. The outer cytosolic face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis. Smooth and rough ER are often attached to each other, but can be distinguished by shape smooth ER is tubular, while rough ER is flatter and the presence or absence of ribosomes on the surface.

While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and There are two basic types of ER. Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough.
Irregular network of membranes coterminous with the outer nuclear membrane in eukaryote cytoplasm that form a meshwork of tubular channels, often expanded into cisternae.
