What is the function of the smooth ER in a factory?
The main function of the smooth ER is to make cellular products like hormones and lipids. What would the nucleolus be in a factory? The nucleolus can be compared to a factory because it's main job is the production of ribosomes.
What is the structure of the smooth ER?
Smooth ER consists of a long network of a folded, tube-like structure. You can think of it like a pipeline with a lot of twists and turns. The interior of the smooth ER is called the lumen, which is enclosed by a phospholipid membrane, just like the membrane that encloses the entire cell.
What is the difference between rough ER and smooth ER?
It is described as 'smooth' to distinguish it from rough ER, which has ribosomes for protein synthesis on its surface. Each organelle in the cytoplasm of a cell is responsible for performing a certain function. Rough and smooth ER each manufacture different products for the cell. Are you a student or a teacher?
How many smooth ER units are in a cell?
The number of smooth ER units in a cell depends on the type of cell and what its manufacturing needs are. These units are situated in the cytoplasm, the gel-like substance inside a cell, and are sometimes connected to a unit of rough endoplasmic reticulum.
What organelle is like a factory?
The ER can be divided into two parts: the rough ER and the smooth ER. The endoplasmic reticulum is like a factory conveyor belt. The steps involved in building a protein. The smooth ER helps transport materials within the cell.
What is a good analogy for smooth endoplasmic reticulum?
Analogy: The smooth endoplasmic reticulum is like a waiter or waitress because he or she helps prepare the food and brings customers their food to be eaten inside the restaurant.
What does the smooth ER do in a plant cell?
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 products are made by the 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.
What would the smooth ER be in a city?
Smooth ER stores ions for later use and calcium for detoxifying substances. They can be similar to roads and highways in cities because vehicles are used to move things and people throughout the city. Rough ER can be seen as an exiting city highway and smooth ER as entering city highway.
How do you compare a cell to a factory?
Cells are similar to factories. To stay alive and function properly, cells have a division of labor similar to that found in factories. All eukaryotic cells are composed of a plasma membrane, a nucleus, and cytoplasm. These structures can be compared with a factory's departments.
In which cell would you find the most smooth ER?
liver cellsLarge amounts of smooth ER are found in liver cells where one of its main functions is to detoxify products of natural metabolism and to endeavour to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
Which group of organelles is involved in manufacturing substances needed by the cell?
So the endoplasmic reticulum is an organelle that's really a workhorse in producing proteins and substances needed by the rest of the cell.
What does a rough ER do?
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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What is smooth ER?
Smooth ER is largely a manufacturing organelle, making and distributing the molecules that a particular type of cell needs. Most smooth ER in both plant and animal cells make lipids, or fatty acids, and so cells involved in lipid manufacturing contain many units of this organelle.
What is the distribution of products in smooth ER?
Distribution of Products. Smooth ER is not just a factory, making needed cellular products. It also has to distribute those products in both animal and plant cells. To do so, small spheres known as vesicles bud off from the membrane of the smooth ER.
What is the smooth endoplasmic reticulum?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function.
Where are smooth ER units located?
The number of smooth ER units in a cell depends on the type of cell and what its manufacturing needs are. These units are situated in the cytoplasm, the gel-like substance inside a cell, and are sometimes connected to a unit of rough endoplasmic reticulum.
What is the ocean side factory?
The ocean-side factory manufactures canned fish products. Each factory makes and distributes the type of product that makes sense for its location. Smooth ER also makes or distributes products according to its location. In muscle cells, it releases calcium ions because they are required for muscle contraction.
Smooth Endoplasmic Reticulum Definition
Eukaryotic cells have a well-defined nucleus and membrane-covered organelles. One such organelle is the endoplasmic reticulum (ER) found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments: rough ER and smooth ER.
Smooth ER Function
What does the smooth ER do? The smooth ER is like a factory that manufactures many products that a cell needs to function. Exactly what it makes depends on the type of cell. Imagine two factories in two different locations. One is in the middle of Florida, while the other is in California.
What is the function of the smooth ER?
The smooth ER (endoplasmic reticulum) function involves manufacturing and packaging, including the synthesis of lipids and hormones which are used for the production of new cellular membranes. The rough ER (endoplasmic reticulum) function involves the assembly of proteins and the transportation of those assembled ready proteins to ...
What is the role of the smooth and rough endoplasmic reticulum in eukaryotic cells
The endoplasmic reticulum is what kicks off the process that will take lipids and proteins to their respective destinations , enabling the body to perform a wide variety of complex actions.
What is the rough endoplasmic reticulum?
The rough endoplasmic reticulum is dubbed “rough” is covered in ribosomes, which gives the organelle a bumpy, rough appearance. Ribosomes are the structures responsible for making proteins, and after the proteins are created they are sent into the lumen. The lumen is the hollow space within the tubules and sacks of the endoplasmic reticulum. Some proteins will remain in the membrane of the ER, while others will be transferred to the ER where they will float around.
Does the smooth endoplasmic reticulum have ribosomes?
The smooth endoplasmic reticulum, as you might have guessed, does not have ribosomes. The functions of the smooth endoplasmic reticulum also differ. The smooth endoplasmic reticulum is involved in the creation of lipids. Lipids refer to any organic compounds which are hydrophobic: they avoid and reject water. The membrane of a cell is made out of a phospholipid bilayer, with a hydrophilic or polar head that interacts with water favorably, and the other side being a hydrophobic fatty acid tail. Some of the lipids include the phospholipids which are used to create new sections of cell membrane and cholesterol which are also used in cell membranes and for the creation of other substances like hormones and vitamin D.
What is an analogy for smooth endoplasmic reticulum?
An analogy for smooth endoplasmic reticulum are the halls of a factory through which information passes. The information in the case of a cell is messenger RNA. A cell is analogous to a factory. Raw materials go into the cell or a factory to produce goods, and the goods depend on the type of cell.
What are the parts of a factory?
The parts of a factory have their equivalents in cells. Cell membranes are like walls, separating each part of the factory or cell. The nucleus of the cell is the headquarters or main office, where the controls are situated.
Which part of the RNA assembly line is the smooth endoplasmic reticulum?
While the smooth endoplasmic reticulum are the hallways through which messenger RNA travels to move information, the rough endoplasmic reticulum is the assembly line where the workers or ribosomes assemble the products, which are the proteins.
