Answer and explanation
Endoplasmic reticulum (ER) is a tubulus membrane that is found in the cytoplasm of the Eukaryote. It's structure consists of the nuclear envelope and the pheripheral endoplasmic reticulum.
Endoplasmic reticulum is divided into 1. smooth ER and 2. rough ER
1. Rough ER - has large numbers of ribosomes attached to the outer surfaces of the lamella membranes, this is the area of ribosomes important for protein production, storage and export. The modified proteins move slowly along the inside of the rough ER until they are packed into small vesicles of the endoplasmic reticulum. After packaging, the proteins are moved by elements of the cytoskeleton either to the Golgi apparatus or to the plasma membrane.
2. Smooth ER - Is involved in the synthesis of steroid. On the surface of smooth ER, there are no ribosomes, therefore it does not participate in the formation of proteins. Its function is to contains many enzymes and other proteins, in liver cells, that have the ability to detoxify a wide range of drugs and poisons.
