What is the function of the rough and smooth endoplasmic reticulum?
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.
How do rough and smooth ER differ?
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 is difference between SER and RER?
Additional Information: -Ribosomes are the protein factory of the cell hence RER functions for protein synthesis….Complete answer:
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| It is structurally more stable. | It is structurally less stable. |
What is the main function of smooth endoplasmic reticulum?
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 do the 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).
Are smooth and rough ER connected?
The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope. The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery.
What do SER and RER have in common?
What are the four major functions of the endoplasmic reticulum?
The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].
What are the functions of rough ER?
The rough ER’s main function is to help form and store proteins, while the smooth ER store lipids, a type of fat. The whole reason why it’s called “rough” is because the ribosomes attaching to it give it a “bumpy” or “rough” appearance.
What are diseases caused by endoplasmic reticulum?
Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease , multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases , and familial encephalopathy with neuroserpin inclusion bodies.
What is an example of an endoplasmic reticulum?
endoplasmic reticulum. The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.
What are the characteristics of the endoplasmic reticulum?
The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells. These sacs and tubules are all interconnected by a single continuous membrane so that the organelle has only one large, highly convoluted and complexly arranged lumen (internal space).
