What are the structural and functional differences between rough 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. It possesses ribosomes attached to its membrane.
What is the difference in structure and function between the SER and the RER?
The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes. SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.
What is the structural difference between rough endoplasmic reticulum and smooth ER quizlet?
Rough endoplasmic reticulum is covered in ribosomes and is involved in the synthesis and production of proteins. Smooth endoplasmic reticulum has no ribosomes and is involved in the production of enzymes and lipids. What is cytoplasm? Identify 2 functions of the cell membrane.
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 are the structural and functional differences between rough ER and smooth ER Why do cells of the testes and adrenal glands have large amounts of smooth ER?
Rough and smooth ER (endoplasmic reticulum) differ in that the rough ER has ribosomes on it. Smooth ER does not have ribosomes and is where steroids are made, which is why there is a lot of smooth ER in cells of the the adrenal gland and sex organs which produce steroid hormones such as estrogen and testosterone.
What is the function of smooth ER?
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.
How does the function of a cell wall differ from the function of the cell membrane?
The cell wall is fully permeable to smaller molecules with the size of 30-60 kDa. The membrane is selectively permeable and controls the movement of the substance into and outside the cell. Functions include protection from the external environment.
What is the difference between rough and smooth endoplasmic reticulum and rough 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 is the difference between the rough and smooth endoplasmic reticulum Flvs?
What is the difference between the rough and smooth endoplasmic reticulum? The surface of rough endoplasmic reticulum is covered in ribosomes, while the smooth endoplasmic reticulum is not covered in ribosomes.
What is the difference between rough ER and smooth ER?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
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 is the rough ER job?
Most endoplasmic reticulum found in cells is rough ER. Due to its affiliation with the ribosomes , the general function of rough ER is to isolate and transport the proteins that have been constructed at the ribosomes. Many of the proteins that are made within a cell are not needed within that cell, but are actually secreted out of the cell.
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).
What does rough ER mean?
Rough Endoplasmic Reticulum Definition. The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER).
