What is a metaphor for smooth endoplasmic reticulum?
smooth endoplasmic reticulum « hallways: Factories have hallways through which information from the office travels to the workers in all departments. Similarly, the cell has smooth endoplasmic reticulum through which it is believed that messenger RNA travels from the nucleus to places where it is decoded.
What does the smooth ER relate to in real life?
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 does the smooth ER do kid friendly?
Smooth endoplasmic reticulum helps make and process lipids and helps detoxify drugs and alcohol.
What would a 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.
What is a real life example of rough endoplasmic reticulum?
A real life example of the Rough Endoplasmic Reticulum would be traffic on a highway.
What is smooth endoplasmic reticulum simple?
Smooth endoplasmic reticulum (sER) is (a part of) endoplasmic reticulum that is tubular in form and lacks ribosomes. It is present in eukaryotic cells and is associated with lipid synthesis, carbohydrate metabolism, regulation of calcium concentration, and drug detoxification.
What is a fun fact about endoplasmic reticulum?
The smooth endoplasmic reticulum also helps detoxify the cell by converting toxic organic chemicals into safer, water soluble products. Fun fact: when there are lots of toxins present, the smooth endoplasmic reticulum can double its surface area to help clear them out.
How is school like a cell?
The Cell Wall is like the beams in a school because it provides the school support. The Chloroplast is like the cafeteria in a school because it is where the students in a school get their energy. The Large Central Vacuole is like a swimming pool because it stores water for the swim team.
What everyday object is like a endoplasmic reticulum?
| Kitchen Analogy | Function |
|---|---|
| Floors or Walkways | The floors or walkways of the kitchen are like the endoplasmic reticulum, because people have to walk on them to get around the kitchen. |
| Garbage Cans & Garbage Disposal | Lysosomes are like garbage cans or garbage disposals because materials are put and broken down in them. |
What part of a city is like the endoplasmic reticulum?
| Cell Part | City Analogy | Purpose |
|---|---|---|
| E. Nuclear Membrane | Police Force | Protects |
| F. Ribosomes | Factory & Workers | Makes products |
| G. Endoplasmic Reticulum | Roads or Highways | Transportation system |
| H. Golgi Bodies | Post Office or UPS | Packs & carries |
Are ribosomes like teachers?
Ribosomes are like teachers in school. Ribosome helps to produce important proteins for a cell and teachers produce educated people. Mitochondrion is like a staff in the school. They act as a powerhouse organelles off the cell getting things done, and the staff do the same, making school run and function.
What does the smooth endoplasmic reticulum do easy definition?
The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism. The smooth ER also regulates and releases calcium ions and processes toxins.
What does smooth ER regulate?
What is the smooth ER made out of?
The smooth endoplasmic reticulum is primarily composed of three-dimensional polygonal networks of tubules called cisternae. They are about 50 nm in diameter in mammals and 30 nm in diameter in yeast.
What is the function of smooth endoplasmic reticulum?
Smooth Endoplasmic Reticulum Definition. The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. It is a subset of the endomembrane system of the endoplasmic reticulum. Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and
What is the function of the sarcoplasmic reticulum?
In muscle cells, the smooth endoplasmic reticulum is called the sarcoplasmic reticulum and is an important locus for the storage of calcium ions. Image shows a skeletal muscle, with the sarcoplasmic reticulum colored blue. Along with special structures in the plasma membrane of the muscle cell
What is the smooth ER and why is it important?
The structure of the smooth ER is of particular significance in two types of cells in the human body – muscle cells and neurons. The presence of an extensive ER network along the neuron is closely associated with its interaction with actin and microtubules and the organelle forms a continuous network across the entire cell.
What is the role of intermediate filaments in the endoplasmic reticulum?
While the formation of the endoplasmic reticulum is dependent on the cytoskeletal machinery of the cell, particularly microtubules, the importance of intermediate filaments is not very clear. The ER is made of tubular cisternae and two-dimensional sheets. However, the diameter of cisternae rarely exceeds 60 nm.
