What is the 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 is the function of rough endoplasmic reticulum quizlet?
Function: Rough endoplasmic reticula are involved in the synthesis of proteins.
What makes the rough endoplasmic reticulum rough quizlet?
Terms in this set (7) It is called ‘rough’ endoplasmic reticulum because it is studded on its outer surface (the surface in contact with the cytosol) with ribosomes.
What makes rough ER rough quizlet?
It is called ‘rough’ endoplasmic reticulum because it is studded on its outer surface (the surface in contact with the cytosol) with ribosomes.
What are the 5 functions of endoplasmic reticulum?
The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].
What is the difference between the rough and smooth endoplasmic reticulum?
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. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
What is the function of rough and smooth endoplasmic reticulum in a plant cell?
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 smooth and rough endoplasmic reticulum?
What is the function of rough endoplasmic reticulum Class 9?
The rough endoplasmic reticulum is named so because of its appearance. It is a series of connected flattened sacs having several ribosomes on its outer surface, hence the name. It synthesizes and secretes proteins in the liver, hormones and other substances in the glands.
What are the two main functions of the rough ER?
What is the main difference between rough ER and smooth ER?
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 are the four functions of endoplasmic reticulum?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. Differences in certain physical and functional characteristics distinguish the two types of ER, known as rough ER (RER) and smooth ER (SER).
What is the difference between rough and smooth endoplasmic reticulum?
RER is found in a lot of cells that are involved in protein synthesis and secretion.
What is analogous to a rough endoplasmic reticulum and why?
Perhaps the clearest analogy that can be made to describe the role of the rough endoplasmic reticulum is that of a factory assembly line. Along its surface, which Dictionary.com describes as “rough” owing to the ribosomes arrayed along its membrane, proteins are synthesized and transported for use in the cell’s chemistry.
What does an endoplasmic reticulum do?
The endoplasmic reticulum, found in eukaryotic cells, is a network of tubes or flat sacs — kind of like a labyrinth of membranes — that serves as the factory of the cell, manufacturing and packaging up proteins and lipids to send around the cell, and even outside of it.
What does the rough endoplasmic reticulum interact with?
Structure of the Rough Endoplasmic Reticulum. The ER can be morphologically divided into two structures–cisternae and sheets.
