Detailed explanation-1: -The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins. Lipids are also produced in the ER.

Detailed explanation-2: -Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Detailed explanation-3: -The endoplasmic reticulum (ER) is a cellular organelle that is a site for calcium storage, lipid biosynthesis, and entry, folding and assembly of proteins destined for the secretory pathway.

Detailed explanation-4: -Proteins and lipids are carried from the ER to the Golgi in transport vesicles that bud from the membrane of the ER and then fuse to form the vesicles and tubules of the ER-Golgi intermediate compartment (ERGIC).

Detailed explanation-5: -The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
