What does SER and RER have in common?
What does SER and RER have in common?
Explanation: The smooth endoplasmic reticulum (SER) is smooth, and the rough endoplasmic reticulum (RER) is rough. Both the SER and RER are large continuous sheets of membrane that fold back on themselves to form an enclosed space (lumen).
What is 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 …
What are the functions of smooth endoplasmic reticulum?
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 is the functional difference between cell and plasma membrane?
Answer: Plasma Membrane is the phospholipid layer, found in all types of cells; it helps in protecting the protoplasm and checks the passage of molecules inside the cell. Cell wall is found in the plant cell, fungi, bacteria only and protects the cell from external shocks, and provide rigidity and shape to the cell.
Do plants have smooth ER?
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells.
What are the differences in structure and function between rough ER and smooth ER?
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 is the difference between rough ER and smooth 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.
What is the difference between smooth endoplasmic reticulum 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. The other major difference between Smooth Endoplasmic Reticulum And Rough Endoplasmic Reticulum are summarized below:
What does the rough and smooth ER do in plant cells?
What does the rough and smooth ER do in a plant cell? 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.
What is the function of rough ER and smooth ER in mitochondria?
Smooth ER: Major function is to synthesis lipids. They also store lipids and proteins. Rough ER: Major function is to synthesize and store proteins.
