Quick Answer: What Is The Smooth ER In A School?

What does the smooth ER do?

The smooth endoplasmic reticulum functions in many metabolic processes.

It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum..

What is the full form of SER and RER?

The ER can be classified in two functionally distinct forms: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER).

Where is smooth ER found?

The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.

Is Er important for membrane biosynthesis?

It helps in manufacturing of lipids and fat molecules. … Endoplasmic reticulum synthesizes lipids (smooth endoplasmic reticulum) and proteins (rough endoplasmic reticulum) which are responsible for formation of membrane. Thus, they help in membrane biogenesis.

Do plant cells have rough ER?

Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.

What would the smooth ER be in a school?

Smooth Endoplasmic Reticulum: The smooth ER is like a school bus because it transports proteins, just like buses transports students to and from school. … The mitochondria are like the main office because it is the power house of the cell, just like the main office is where the main flow of power lies in a school.

What is the smooth ER made of?

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 …

What is the difference between rough ER and smooth ER?

Both rough ER and smooth ER have the same types of membranes but they have different shapes. 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. … Smooth ER (SER) acts as a storage organelle.

What diseases does the endoplasmic reticulum cause?

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 are the functions of RER and SER?

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 does rough ER mean?

Rough endoplasmic reticulumAlternative Titles: RER, rough ER. Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What is the smooth ER similar to?

Both rough ER and smooth ER have the same types of membranes but they have different shapes. 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.

What is the difference between SER and RER?

The most basic difference between RER and SER is the presence of ribosomes….Difference between Smooth and Rough Endoplasmic Reticulum.Rough Endoplasmic Reticulum (RER)Smooth Endoplasmic Reticulum (SER)Provides proteins and lipids for Golgi apparatus.Provides vesicles for cis-face of Golgi apparatus.7 more rows

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.
