network of membranes in cells for protein and lipid synthesis
The Endoplasmic Reticulum (ER) is a network of membranes within a cell that plays a crucial role in the synthesis, folding, modification, and transport of proteins and lipids. There are two types: Rough ER, which is studded with ribosomes and primarily involved in protein synthesis, and Smooth ER, which lacks ribosomes and is involved in lipid synthesis and detoxification processes.
