Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The function of the rough ER is to:
A
Produce and folding lipids
B
Produce and folding proteins
C
Produce and folding carbohydrates
D
Produce and folding Nucleic acids
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Proteins synthesized by the rough ER include the prominent milk protein casein, and whey proteins. These proteins are packaged into secretory vesicles or large micelles and travel through the Golgi network before fusing with the plasma membrane, releasing their contents into milk ducts.

Detailed explanation-3: -A newly synthesized protein entering the endoplasmic reticulum (ER) undergoes a series of modifications and encounters a number of molecular chaperones and folding enzymes that all together assist its proper folding and subsequent release from the ER.
