Question

Write the function of the smooth endoplasmic recticulum and rough endoplasmic recticulum.

Answer 1

Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids.


The Rough ER is also attached to the nuclear envelope that surrounds the nucleus. This direct connection between the perinuclear space and the lumen of the ER allows for the movement of molecules through both membranes.

The process of protein synthesis starts when mRNA moves from the nucleus to a ribosome on the surface of the RER.
