What can the smooth ER be compared to in a school?

The Smooth ER is structure that does not contain ribosomes and is the passageway from the nucleus that transports lipids (fats) throughout the cell. The School Bus transports students to the school like the Smooth ER transports the Lipids.

What would the smooth ER be in a house?

Endoplasmic Reticulum

The Rough ER has ribosomes studded on it. It can be compared to a hallway with different rooms branching off of it. The other kind of ER is the smooth ER, which can be thought of as a hallway in a home that only leads from point A to point B.

What would 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 object is the smooth ER similar to?

A smooth ER is a membrane system with other functions depending on types of cells. It resembles a water. Depending on what you mix it with, it becomes a different drink.

What is an analogy for proteins?

This string of pearls is a good visual analogy for a protein. Pearls are the building blocks of a pearl necklace and amino acids are the building blocks of a protein. They are bound to each other and form a chain. Now proteins don’t typically exist as shapeless strings of amino acids.

What is a cell like analogy?

Teachers often assign cell analogy projects for this reason. A cell analogy project requires a real-life place or object in place of a cell that describes how the place’s or object’s components are like those of a cell.

How are rough and smooth ER similar?

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 a good analogy for cell membrane?

The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate. 4. Cell Wall -Supports and protects the cell while still letting materials pass through it.

What is the smooth ER compared to in real life?

Smooth ER is a tube-like structure with a long network of folded tubes. It’s similar to a pipeline with a lot of bends and turns. The lumen, the interior of the smooth ER, is surrounded by a phospholipid membrane, similar to the membrane that encloses the entire cell.

How do rough and smooth ER compare structurally and functionally?

Describe the structural and functional distinctions between rough and smooth ER. The primary distinction between rough and smooth ER is the presence of bound ribosomes on the rough ER. … The smooth ER also functions in detoxification, carbohydrate metabolism, and storage of calcium ions.

How do the ER and cell membrane work together?

Membranes and their constituent proteins are assembled in the ER. This organelle contains the enzymes involved in lipid synthesis, and as lipids are manufactured in the ER, they are inserted into the organelle’s own membranes. This happens in part because the lipids are too hydrophobic to dissolve into the cytoplasm.

What is the difference between smooth ER rough ER and Golgi apparatus?

Rough ER provides proteins and lipids for the Golgi apparatus. Smooth ER provides vesicles for the cis-face of the Golgi apparatus. The rough endoplasmic reticulum is mostly associated with the production, modification, and transfer of proteins.

Does the smooth endoplasmic reticulum have ribosomes?

Smooth endoplasmic reticulum, ( SER), has been found involved in organic compound synthesis. SER does not have ribosomes on its surface, however, and thus does not participate in the making of proteins.

What is smooth endoplasmic reticulum Class 9?

The smooth endoplasmic reticulum has a tubular form. It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism. Smooth ER transports the products of the rough ER to other cellular organelles, especially the Golgi apparatus.

What is the difference between the rough and smooth endoplasmic reticulum 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.

Why are ribosomes attached to endoplasmic reticulum?

Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. … When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.

How do the ER and ribosomes work together?

Ribosomes are the organelles for protein synthesis. When ribosomes translate proteins on surface of endoplasmic reticulum (ER), such proteins are directly delivered within the lumen of ER. ER with ribosomes scattered on surface is called rough ER (=RER). Its lumen gets supply of proteins.

What attaches carbohydrates to proteins?

Glycoproteins
Glycoproteins are proteins which contain oligosaccharide chains (glycans) covalently attached to amino acid side-chains. The carbohydrate is attached to the protein in a cotranslational or posttranslational modification. This process is known as glycosylation. Secreted extracellular proteins are often glycosylated.

What are attached ribosomes?

Attached, or bound, ribosomes are found on the exterior of an organelle called the endoplasmic reticulum. … Attached ribosomes are responsible for generating proteins which will be part of a membrane or which will be stored in units called vesicles.

When ribosomes attached to the endoplasmic reticulum it is called?

If the endoplasmic reticulum (ER) has ribosomes attached to it, it is called rough ER; if it does not, then it is called smooth ER. The proteins made by the rough endoplasmic reticulum are for use outside of the cell.

Does smooth ER make proteins?

sER is a membrane-bound network of tubules (see Figs. 1-1 and 1-3) without surface ribosomes. sER is not involved in protein synthesis. Its main function is the synthesis of lipids, organic compounds, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
