Answer 1

Answer:

Endoplasmic reticulum is a cell organelle which help in protein synthesis, digestion etc. It has two types 1.SER - Smooth endoplasmic reticulum 2.RER - Rough endoplasmic reticulum....

Answer 2

“Endoplasmic Reticulum is a complex network of tubular membranes exclusively present in the cytoplasm of the eukaryotic cell.”

Endoplasmic Reticulum Function

As stated above, the endoplasmic reticulum is categorised into two types, and both these types of ER perform specific functions:

Smooth Endoplasmic Reticulum Function:

Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol.

Smooth ER is also responsible for the production and secretion of steroid hormones.

It is also responsible for the metabolism of carbohydrates.

The smooth ER store and release calcium ions. These are quite important for the nervous system and muscular system.

Rough Endoplasmic Reticulum Function:

The majority of the functions of rough ER plays is associated with protein synthesis.

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.
