The Endoplasmic Reticulum, or ER, is a multifaceted organelle that plays a pivotal role in a cell. It is responsible for the synthesis of proteins and lipids necessary for the cell's function.

Structure
The ER consists of a network of membranous sacs and tubes throughout the cell's cytoplasm.
There are two types of Endoplasmic Reticulum.

• Rough ER
This type is studded with Ribosomes, responsible for protein synthesis.
• Smooth ER
This type synthesizes lipids, metabolizes carbohydrates, and detoxifies the cell.

Synergy
Rough ERs have Ribosomes.
Proteins and lipids from the ER can be packaged by the Golgi Complex.
