Whats the difference between rough ER and smooth ER?

The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.

How is rough er different from smooth ER What functions do they perform in a cell class 9?

Rough ER is different from smooth ER in having ribosomes (protein units ) on its surface. ... The Ribosomes present in RER are the structures responsible for making proteins which are further sent to the lumen . It is also responsible for making phospholipids which make up the membranes of cells. Hope that helps !

What does smooth and rough ER do?

The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.

What does the smooth ER do?

smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular ...

Why is the rough ER important?

The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Rough ER is the organelle that reads the DNA instructions to make the proteins. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus.

How do rough and smooth ER compare structurally and functionally?

Describe the structural and functional distinctions between rough and smooth ER. The primary distinction between rough and smooth ER is the presence of bound ribosomes on the rough ER. ... The smooth ER also functions in detoxification, carbohydrate metabolism, and storage of calcium ions.

What is the difference between smooth and rough surface?

is that rough is having a texture that has much friction not smooth; uneven while smooth is having a texture that lacks friction not rough.

What is smooth endoplasmic reticulum Class 9?

The smooth endoplasmic reticulum has a tubular form. It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism. Smooth ER transports the products of the rough ER to other cellular organelles, especially the Golgi apparatus.

What organelles does the smooth ER work with?

While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.

What does a ribosome do?

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

What would happen without the rough ER?

What would happen if there wasn't an endoplasmic reticulum. As we've already covered the ER produces ribosomes,and without these ribosomes the cell would not be able to use synthesis to split and create more cells. It also produces things like steroids and without these the plant cell would die.

How does the structure of the smooth ER aid in the function?

The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. ... Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell.

Which surface have more friction rough or smooth Why?

A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction.

What is the difference between hard and soft and rough and smooth materials?

the material having irregularity in their surface is called rough material. the material having smoothness in their surface is called smooth material.
