Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the general physiology (function) of the ER?
A
to fold, and transport proteins and lipids
B
to make proteins
C
to discard vacuoles
D
connect with the Golgi through its interconnected tubes
Explanation: 

Detailed explanation-1: -The majority of the functions of rough ER is associated with protein synthesis. The rough endoplasmic reticulum also plays a vital role in protein folding. Also ensures quality control (regarding correct protein folding). The second most important function after protein synthesis and protein folding is protein sorting.

Detailed explanation-2: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.

Detailed explanation-3: -Summary. The endoplasmic reticulum is a network of phospholipid membranes that form hollow tubes, cisternae, and vesicles. The ER is involved in transport of molecules, such as proteins, and the synthesis of proteins and lipids. The ER can be rough, with embedded ribosomes, or smooth, without ribosomes.
