Question

What is the significance of presence of ribosomes on RER

Answer 1

it helps in producing synthetic protein , RER also helps in the process of
membrane biogenesis  

Answer 2

Significance of presence of Ribosome on Rough Endoplasmic Reticulum is that it is involved in protein secretion.

Explanation:

Ribosomes present on the rough endoplasmic reticulum are called membrane bond structure and are in charge of the collection of numerous proteins. This procedure is known as translation.

The rough ER along with layer bound ribosomes takes polypeptides and amino acids from the cytosol and proceeds with the formation of protein by collecting and joining amino acids.
