What is the smooth endoplasmic reticulum function?
What is the smooth endoplasmic reticulum function?
Smooth Endoplasmic Reticulum Function: Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. Smooth ER is also responsible for the production and secretion of steroid hormones. It is also responsible for the metabolism of carbohydrates.
What’s the difference between smooth and rough ER?
When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane. It does not have ribosomes on its membrane.
What is the difference between rough and smooth endoplasmic reticulum?
Smooth Endoplasmic Reticulum does not have ribosomes on its membrane. Rough Endoplasmic Reticulum possesses ribosomes attached to its membrane. It is organized of vesicles and tubules. It is organized of cisternae and a few tubules.
What is smooth and rough endoplasmic reticulum?
The smooth endoplasmic reticulum (SER) is distinguished from the rough endoplasmic reticulum (RER), the other basic type of endoplasmic reticulum, by its lack of ribosomes, which are protein-synthesizing particles that can be found attached to the outer surface of the RER to give the membrane its “rough” appearance.
What is difference between SER and RER?
The main difference between the rough endoplasmic reticulum and smooth endoplasmic reticulum is that RER consists of ribosomes that are responsible for its rough nature and synthesis of protein. It plays a central role in protein synthesis. It plays an important role in lipid synthesis.
What is difference between smooth ER and rough ER?
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
What is the role of SER?
The functions of SER can vary to an extent depending on the type of cell. More commonly, it is concerned with carrying out certain metabolic processes. Smooth Endoplasmic Reticulum (SER) is mainly concerned with the synthesis of carbohydrate and lipids, and sometimes, with their metabolism.
What is the function of SER?
SER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In cells of the liver, SER contributes to the detoxification of drugs and harmful chemicals.
What is smooth ER and rough ER?
Smooth Endoplasmic Reticulum does not have ribosomes on its membrane. Rough Endoplasmic Reticulum possesses ribosomes attached to its membrane. Organized. It is organized of vesicles and tubules. It is organized of cisternae and a few tubules.
What is the difference between smooth and rough ER explain?
Its rough appearance is given by the bound ribosomes on its surface. Rough ER synthesizes and stores proteins. Smooth ER, on the other hand, helps in the storage of proteins and lipids. The main difference between smooth and rough ER is that smooth ER lacks bound ribosomes whereas rough ER is bound with ribosomes.
What does an endoplasmic reticulum do?
The endoplasmic reticulum, found in eukaryotic cells, is a network of tubes or flat sacs — kind of like a labyrinth of membranes — that serves as the factory of the cell, manufacturing and packaging up proteins and lipids to send around the cell, and even outside of it.
What would happen if the smooth ER stopped working?
What would happen if the smooth ER in the cell were destroyed? a. The cell would be unable to produce glucose. b. The cell would no longer be able to produce proteins. c. The cell would not be able to make enough ATP through respiration. d. The cell would not be abel to make lipids or break down poisons.
What is the function of smooth ER?
Production of ATP. Perhaps the most well-known role of mitochondria is the production of ATP,the energy currency of cells.…
What is the function of the rough endoplasmic reticulum?
Structure of the Rough Endoplasmic Reticulum. The ER can be morphologically divided into two structures–cisternae and sheets.
