What is the function of the Endoplasmic Reticulum (ER)?
A
Package and ship proteins
B
Transport proteins
C
Create energy for the cell
D
Remove waste
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.

Detailed explanation-3: -The RER is also located near the Golgi apparatus, which transports, modifies, and packages proteins for delivery to targeted destinations. Many proteins that are synthesized in the RER are packaged into vesicles and transported to the Golgi apparatus.

Detailed explanation-4: -The rough endoplasmic reticulum works with the Golgi apparatus to move new proteins to their proper destinations in the cell.

Detailed explanation-5: -The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
