Answer 2

Given Question :

What is endoplasmic reticulum? Write its functions.

Required Answer :

$\purple \bigstar$ Endoplasmic reticulum is a membranous network enclosing a fluid-filled lumen which almost fills up the intracellular cavity.

Functions :

• Smooth endoplasmic reticulum is responsible for the synthesis of lipids, fats, steroids.

• Rough endoplasmic reticulum is responsible for the synthesis of proteins.

• Endoplasmic reticulum forms supporting skeletal framework of the cell.

• Smooth endoplasmic reticulum also helps in detoxification.

• Endoplasmic reticulum also helps in the formation of plasma membrane and other cellular membranes.

• Digestive enzymes of lysosomes are also produced by the rough endoplasmic reticulum. $\purple \bigstar$

More Details -

There are mainly two types of Endoplasmic reticulum :

• Smooth endoplasmic reticulum - These are the types of Endoplasmic Reticulum which have ribosomes attached on its surface for synthesizing proteins.

» It is formed of vesicles and tubules

» Smooth endoplasmic reticulum plays an important role in the biosynthesis of glycolipids phospholipids and cholesterol.

• Rough endoplasmic reticulum - These are the types of Endoplasmic Reticulum which are without ribosomes and is meant for secreting lipids.

» It contains flattened sacs called cisternae.
