Explanation:

What is the work of Endoplasmic reticulum in a cell?

=> Endoplasmic Reticulum has one of the most important work to do inside the cell which is protien modification(post translational modification) and even the synthesis of fatty acids.

There are two types of ER

1.SER(smooth endoplasmic Reticulum)

2.RER(rough endoplasmic Reticulum)

In the case of post translational modification ER is the must needed orgenelle it will add or splice the structure of protein as what is required. It will help protein in folding and even they also regulates the degradation of protein which are not folded properly or which should be degraded. After the post translational modification ER sends the protein to golgy complex. In the post translational modification some groups or molecules are added to the protein structure for example addition of sugar molecules(in the case of glycoproteins), fatty acid chain(in the case of lipoproteins), combining two or more subunits(in the case of multiunit or oligomeric proteins), addition of phosphate activity, addition of other molecules, removing some extra amino acids or poly peptide chain etc.

In the case of fatty acid synthesis specially they synthesising fatty of medium chain fatty acid. SER are mostly accounts with fatty acid synthesis.

Answer 2

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
