Question

What is endoplasmic reticulum? Name its type and function​

Answer 1

Answer:

The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.

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

⭐Types:-

There are two types of Endoplasmic Reticulum :-

• Rough ER
• Smooth ER

Rough endoplasmic reticulum has ribosomes embedded within its structure, giving a “rough” appearance. Smooth endoplasmic reticulum does not have these ribosomes, hence appear “smooth.”

⭐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 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.
