Quick Answer: What Does The Smooth ER Do?

What is the function of SER and RER?

RER helps in the formation of proteins in the cell.

The presence of ribosomes is actually responsible for the synthesis of the proteins by the RER….RER-Rough Endoplasmic ReticulumSER-Smooth Endoplasmic ReticulumTheir function is to synthesize proteins.Their function is to synthesize lipids.6 more rows.

What is the rough endoplasmic reticulum like in real life?

Thee proteins on the ribosomes collect in the Endoplasmic Reticulum to help transport the proteins throughout the cell. It is responsible for protein synthesis. A real life example of the Rough Endoplasmic Reticulum would be traffic on a highway.

What does ER RER and SER stand for?

SER- It stands for Smooth Endoplasmic Reticulum. It helps in the synthesis of Lipids for membrane biogenesis. RER- It stands for Rough Endoplasmic Reticulum. It helps in the synthesis of Plastids for membrane biogenesis.

What happens if the Golgi body is missing?

Without Golgi bodies, there would be no way for cells to prepare proteins and lipids for transport to other locations within or outside the cell. … Without Golgi bodies, there would also be no way for the cell to produce a number of different macromolecules or transport enzymes out of the cell.

What does smooth ER regulate?

The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism. The smooth ER also regulates and releases calcium ions and processes toxins.

What happens if the smooth ER is missing?

The smooth ER has an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well. Without the RER the cell is not able to synthesis new plasma membrane proteins, lysosomal enzymes, proteines for the Golgi apparatus and proteins for extracellular secretion.

What does the smooth ER look like?

Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen.

How does the smooth ER detoxify drugs?

The enzymes that synthesize the lipid components of lipoproteins are located in the membrane of the smooth ER, which also contains enzymes that catalyze a series of reactions to detoxify both lipid-soluble drugs and various harmful compounds produced by metabolism.

What can a cell be compared to?

A cell can be compared to a houseThe rough endoplasmic reticulum of the cell is like the hallways in a house because they transport people throughout the home like the rough ER transports materials throughout the cell.Sources:The mitochondria of the cell are like the fuse box of a house. … Ribosomes are like an oven.More items…

How does the smooth ER make lipids?

The ribosomes on the rough endoplasmic reticulum manufacture proteins which enter the channels of the endoplasmic reticulum and move to places where they can create pockets. … The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes.

What would smooth ER be in a city?

Both the smooth and rough endoplasmic reticulum would be the various highways and roads in cell city. … Smooth ER stores ions for later use and calcium for detoxifying substances. They can be similar to roads and highways in cities because vehicles are used to move things and people throughout the city.

What is bad about the endoplasmic reticulum?

There is accumulating evidence implicating prolonged ER stress in the development and progression of many diseases, including neurodegeneration, atherosclerosis, type 2 diabetes, liver disease, and cancer.

What is the function of RER Class 9?

1)It provides a pathway for distribution of nuclear material from one cell to other. 2)Certain enzymes present in SER synthesise fat,steroids,cholesterol. 3)RER help in transport of protein which are synthesised by ribosomes on their surface.

What is a good analogy for a cell?

In a cell, the endoplasmic reticulum helps with the transport of material through the cell; In a car, the fuel line provides fuel to the engine from the gas tank. A car’s driver is equivalent to the nucleus of a cell. If the driver does not step on the gas, the car does not move.

Why is a cell compared to a city?

The nucleus controls all of the activities of the cell as city hall controls all the activities in of the city. 2. The cell membrane is a thin, flexible envelope that surrounds the cell. … The cell membrane controls what goes into and out of the cell as the city limits control what goes in and out of the city.

What are 3 jobs of the smooth ER?

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.

Where is the rough ER located?

Rough ER lies immediately adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope. The ribosomes on rough ER specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the ER for processing.

What is the difference between the RER and SER?

The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes. SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.

How does the rough ER get energy?

The ribosomes that are attached to the walls of the rough endoplasmic reticulum function just like free ribosomes would. That means that they synthesize proteins, which provide the energy needed for a cell to operate. … There are certain proteins that are sent into the space within the rough endoplasmic reticulum.
