Question: Where Is Smooth ER Found?

What is the smooth endoplasmic reticulum like in real life?

The Smooth Endoplasmic Reticulum is considered smooth because of its smooth appearance.

The smooth endoplasmic reticulum is responsible for lipid synthesis.

It processes a variety of metabolic processes such as drug detoxification A real life example would be a high way..

What does a cell represents in a real life?

Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.

What cells have a lot of smooth endoplasmic reticulum?

The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification. The smooth endoplasmic reticulum is especially abundant in mammalian liver and gonad cells.

What happens if the rough ER is damaged?

Protein Folding in the Rough ER Protein folding generally happens in the interior of the RER. … Misfolded proteins may not function properly, and this malfunction can even cause human disease.

Why do alcoholics have more smooth ER?

Alcoholics have a lot more Smooth ER than people who don’t drink. As people consume more alcohol, they realize that they have to continue to drink more to get the same effect. This happens because more inactivating enzymes are being produced. These inactivating enzymes are responsible for helping to detoxify the liver.

What are the functions of RER and SER?

RER helps in the formation of proteins in the cell. The presence of ribosomes is actually responsible for the synthesis of the proteins by the RER….RER-Rough Endoplasmic ReticulumSER-Smooth Endoplasmic ReticulumTheir function is to synthesize proteins.Their function is to synthesize lipids.6 more rows

What is most likely to have the greatest concentration of smooth endoplasmic reticulum?

Answer. Answer: Cellsthat make steroid hormones have higher smooth endoplasmic reticulum.

Where is the smooth ER located?

In muscle cells, the smooth endoplasmic reticulum regulates calcium ion storage. 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.

Is smooth endoplasmic reticulum found in plant or animal cells?

Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.

Is smooth ER found in all cells?

All eukaryotic cells contain an ER. In animal cells, the ER usually constitutes more than half of the membranous content of the cell. The ER can be classified in two functionally distinct forms: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER).

Where is the smooth ER most plentiful?

Large amounts of smooth endoplasmic reticulum are found in cells that specialize in lipid metabolism. For instance, liver cells remove alcohol and drugs from the bloodstream. Liver cells have an impressive network of smooth endoplasmic reticulum.

Do bacteria have ER?

many membrane bound organelles- lysosomes, mitochondria (with small ribosomes), golgi bodies, endoplasmic reticulum, nucleus. Large ribosomes in cytoplasm and on rough ER. … Bacteria, of course, have no nucleus and therefore also nuclear membrane.

What is a real life example of a Golgi body?

Golgi body can be the secretaries or the assisting managers which supports, checks, modifies and confirms the many tasks before it is passed into the nucleus and other organelles, they also dissiminate information.

Where do lipids go after smooth ER?

Both proteins and lipids move from the ER to the Golgi apparati and on to other destinations by transport in vesicles that bud off from one cellular compartment and fuse with the next.

What would happen without the smooth ER?

The smooth ER has an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well. Without ER in the skeletal muscle fibers couldn’t happen muscle contraction. In the absence of these cellular mechanisms the cell would probably die.

What is the difference between rough ER and smooth ER?

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.

Why is the smooth ER important?

The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors. In addition, it is involved in carbohydrate metabolism.

What is a real life example of a cell wall?

If a plant cell is like a water balloon, the cell wall is like a cardboard box that protects the balloon. The balloon is protected from the outside world by a structure that provides protection and support.

What is the structure of the rough ER?

The rough endoplasmic reticulum is largely made of sheets – a two-dimensional array of flattened sacs that extend across the cytoplasm. In addition to ribosomes, these membranes contain an important protein complex called the translocon, which is necessary for protein translation within the rough ER.

What is the purpose of the endoplasmic 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.
