Explanation:
Detailed explanation-1: -The ER has a central role in lipid and protein biosynthesis. Its membrane is the site of production of all the transmembrane proteins and lipids for most of the cell’s organelles, including the ER itself, the Golgi apparatus, lysosomes, endosomes, secretory vesicles, and the plasma membrane.
Detailed explanation-2: -Endoplasmic reticulum (ER) is known as the maze of folded membranes where proteins and lipids are produced. The ER is a complex organelle composed of membranous flattened sacs, cylinders, and vesicles.
Detailed explanation-3: -Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.
