Endoplasmic reticulum


Rough endoplasmic reticulum contains the majority of the cell’s ribosomes, with the ribosomes studding its surface.

Functions as the location for membrane and secretory protein production as well as protein modification.

Endoplasmic reticulum (ER): This functions to synthesize, store, and secrete proteins to the Golgi apparatus.

Most developed in cells that produce for secretions.

A lacelike network composed of membranes enclosing interconnecting cisterns.

Rough endoplasmic reticulum contains ribosomes and is associated with protein production.

Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.

The membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the ER.

Smooth endoplasmic reticulum is the site of production of lipids and site of lipolysis.

The smooth endoplasmic reticulum is the site of fatty acid and phospholipids production.

Most cells have small smooth endoplasmic reticulum but cells like hepatocytes, that are actively detoxifying hydrophobic compounds through conjugation and excretion, are well developed.
