Endoplasmic Reticulum: For Those who Multi-Task
Endoplasmic Reticulum is an organelle found in all eukaryotic cells responsible for several functions within the cell. The ER consists of a network of membranous tubules and sacs called cisternae, and is continuous with the nuclear envelope. There are, however, two types of ER--Smooth ER and Rough ER. The only difference between the two is that Rough ER contains ribosomes on it's surface and has separate functions (See photo above).
Functions of Smooth ER, many involving help of enzymes within it, include the synthesis of lipids, metabolism of carbohydrates, and detoxification drugs and poisons dangerous to the cell.
Rough ER has many different functions because the ribosomes attached to it's cisternae are involved in creating many different proteins. Their functions include the synthesis of secretory proteins, and assisting membrane production by growing in place with the addition of proteins and phospholipids.
