What are functions of Endoplamic reticulum?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
What type of cell is RER found in?
eukaryotic cells
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 structure and function of Golgi apparatus?
The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.
What does SER and RER produce?
The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. hence, SER produce lipids…….and RER produce proteins………….
What is the difference 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 are the two types of endoplasmic reticulum and what are their functions?
The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.
What is the rough endoplasmic reticulum?
What is rough endoplasmic reticulum? The rough endoplasmic reticulum is a membraneous organelle that functions to produce proteins with the help of ribosomes on the membrane surface.
Why is Golgi apparatus important?
The Golgi apparatus plays a major role in protein biosynthesis, post-translational modification of endoplasmic reticulum (ER) derived proteins and as a sorting station for proteins directed for the plasma membrane, lysosomes and other destinations.
What are the four functions of the Golgi apparatus?
What are the four functions of the Golgi apparatus?
- Modifying of proteins.
- Sorting and processing of proteins.
- Creating the lysosomes.
- Transporting lipids around the cell.
What is difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
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 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.
