What are three differences between the smooth and Rough ER?

What are three differences between the smooth and Rough ER?

Smooth endoplasmic reticulum (SER) is a type of endoplasmic reticulum consisting of tubular vesicles that lack ribosomes on the outer surface and is involved in the synthesis and storage of lipids. Rough ER has ribosomes on the outer surface. Smooth ER doesn’ thave ribosomes on the outer surface.

What is the difference between the smooth and rough endoplasmic reticulum what are their functions?

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 are the functions of SER and RER?

Introduction on Rough and Smooth Endoplasmic Reticulum

RER-Rough Endoplasmic Reticulum	SER-Smooth Endoplasmic Reticulum
They are found near the nucleus of the cell.	They are found away from the nucleus in the cell.
Their function is to synthesize proteins.	Their function is to synthesize lipids.

What is the meaning of RER and SER?

RER stands for Rough Endoplasmic Reticulum. It is a cell organelle which is called ” rough ” since it has small structures called ribosomes which help in synthesizing proteins. SER stands for Smooth Endoplasmic Reticulum. It is a cell organelle which manufacturers compounds like fat molecules called Lipids .

What are the two main functions of the Smooth Endoplasmic Reticulum?

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. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.

What are the functions of rough ER?

The rough ER’s main function is to help form and store proteins, while the smooth ER store lipids, a type of fat. The whole reason why it’s called “rough” is because the ribosomes attaching to it give it a “bumpy” or “rough” appearance.

What is the rough ER job?

Most endoplasmic reticulum found in cells is rough ER. Due to its affiliation with the ribosomes , the general function of rough ER is to isolate and transport the proteins that have been constructed at the ribosomes. Many of the proteins that are made within a cell are not needed within that cell, but are actually secreted out of the cell.

What are the characteristics of the endoplasmic reticulum?

The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells. These sacs and tubules are all interconnected by a single continuous membrane so that the organelle has only one large, highly convoluted and complexly arranged lumen (internal space).

What does rough ER mean?

Rough Endoplasmic Reticulum Definition. The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER).
