What is the function of endoplasmic reticulunm?

Answer 1

translation and folding of new proteins (rough endoplasmic reticulum), expression of lipids (smooth endoplasmic reticulum)

Answer 2

The endoplasmic reticulum (ER) is responsible for protein and lipid synthesis, as well as for the transport of these molecules within the cell. It plays a crucial role in the synthesis, folding, and modification of proteins before they are transported to their final destination within or outside the cell.

Answer 3

The rough ER is the site of protein modification and folding of proteins, if they need folding. The smooth ER is the site of lipid and steroid synthesis.
