How does the smooth and rough endoplasmic reticulum differ?

How does the smooth and rough endoplasmic reticulum differ?

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 is the rough ER doing that is different in each case?

What does the endoplasmic reticulum do? Rough ER has ribosomes attached to it that make proteins and lipids. Smooth ER doesn’t have ribosomes and can be used for storage and for making lipids.

What do the SER and RER have in common?

Explanation: The smooth endoplasmic reticulum (SER) is smooth, and the rough endoplasmic reticulum (RER) is rough. Both the SER and RER are large continuous sheets of membrane that fold back on themselves to form an enclosed space (lumen).

How is RER different from SER How do these two differ in their functions mention how these two come together for the synthesis of a major part of the cell?

RER is the rough endoplasmic reticulum which has ribosomes attached on it’s surface whereas SER is the smooth endoplasmic reticulum which doesn’t have any other material attaxhed to its surface. SER plays a crucial role in detoxifying poisons .

What is the function of rough and smooth endoplasmic reticulum?

The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.

What is the difference between rough and smooth ER Brainly?

Answer: The difference lies between the two is that the Smooth Endoplasmic Reticulum is not bounded by the ribosomes and is known for storing the lipids and proteins. Meanwhile, the Rough Endoplasmic Reticulum is bounded by the ribosomes and store proteins.

What covers and protects the nucleus?

The nucleus contains all of the genetic material for a eukaryotic cell, but this genetic material needs to be protected. And it’s protected by the nuclear membrane, which is a double membrane that encloses all the nuclear genetic material and all the other components of the nucleus.

What is the major morphological difference between the SER and RER?

The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.

What is the function of RER and SER Class 9?

2)Certain enzymes present in SER synthesise fat,steroids,cholesterol. 3)RER help in transport of protein which are synthesised by ribosomes on their surface. 5)It function as cytoplasmic framework providing a surface for some of the biochemical activities of the cell.

What is the main function of the rough 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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

What’s the difference between a RER and a ser?

Rough Endoplasmic Reticulum (RER) Smooth Endoplasmic Reticulum (SER) It possesses ribosomes attached to its membrane. It does not have ribosomes on its membrane. Formed of cisternae and a few tubules. Formed of vesicles and tubules. It participates in the synthesis of enzymes and proteins.

What’s the difference between RER and rough ER?

Due to the presence of small granular ribosomes that are present on the surface of ER they are termed as Rough ER. RER has a number of flattened tubules that are joined with each other. They are highly dense near to the nuclear membrane. These are highly convoluted tubules. RER helps in the formation of proteins in the cell.

What makes an ER different from a reticulum?

Structurally, there are two types of endoplasmic reticulum in a cell. They are: 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.

Why does the RER look like an uneven surface?

Rough Endoplasmic Reticulum or RER looks like an uneven surface because of the presence of the 80S ribosomes, when viewed in the electron microscope. It is also known as the Granular Endoplasmic Reticulum. The main function of the RER is to take part in the protein synthesis and helps in the transportation of the protein to other parts.
