What is endoplasmic reticulum?

Question

Answer

The large network of membranous sheets and tubes is called endoplasmic reticulum. They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell.Hope it will help you!Regards!

Answer

Endoplasmic Reticulum is a cell membrane have oblong structure mainly situated near nucleus .It has two types (rough ER and (Smooth ER) rough ER contains ribosomes which helps for making of protein by the DNA that's it is near to Nick whereas smooth ER is little far to nucleus as it helps to making of fat.ER 's main function is to making of these lipids or fats for the new cell membrane for our body....m sorry I don't know about it as much cuz our teacher continues to these chapter hops it can help u

Answer

Endoplasmic reticulum is network of membrane bound cavities_____
Endoplasmic reticulum is cell organelle which is of two types (1) Rough endoplasmic reticulum(RER) &
(2) Smooth endoplasmic reticulum (SER) ________
(1)RER ::: Have ribosomes attached to ER membrane ____
(2)SER:::: Not having ribosomes attached to ER membrane ______

Answer

The endoplasmic reticulum is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. The membranes of the ER are continuous with the outer nuclear membrane.

Answer

What is Endoplasmic Reticulum?
The endoplasmic reticulum (ER) is a vital organelle found in eukaryotic cells. It plays a key role in the synthesis, folding, modification, and transport of proteins and lipids.

Types of Endoplasmic Reticulum
- Smooth ER:
- Lacks ribosomes on its surface.
- Involved in lipid synthesis, detoxification, and calcium ion storage.
- Rough ER:
- Studded with ribosomes, giving it a 'rough' appearance.
- Primarily responsible for the synthesis of proteins destined for secretion or for use in the cell membrane.

Functions of Endoplasmic Reticulum
- Protein Synthesis:
- Rough ER provides a site for ribosomes to translate mRNA into polypeptide chains, which then fold into functional proteins.
- Lipid MetabolismDetoxification:
- Smooth ER helps in the detoxification of drugs and poisons, particularly in liver cells.
- Calcium Storage:
- The ER serves as a reservoir for calcium ions, crucial for various cellular activities including muscle contraction.

Importance in Cellular Function
The endoplasmic reticulum is essential for maintaining homeostasis within the cell. Its ability to synthesize and transport proteins and lipids is crucial for cellular structure and function. Disruptions in ER function can lead to diseases, highlighting its importance in cellular health.
Overall, the endoplasmic reticulum is a complex and multifunctional organelle, central to the life of eukaryotic cells.
