Endoplasmic reticulum (ER) is a cellular organelle. It is the transport network for molecules going to specific places, as compared to molecules that float freely in the cytoplasm . ... Rough endoplasmic reticulum (RER), so called because it is studded with ribosomes, and secretes proteins into the cytoplasm.
What does the endoplasmic reticulum do kid definition?
Endoplasmic reticulum is a collection of tubes that make, package, and transport proteins and fats . Rough endoplasmic reticulum has protein-making ribosomes on its surface, so it helps make and process proteins.
What does the endoplasmic reticulum do easy definition?
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move . Proteins are assembled at organelles called ribosomes. ... Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
What is endoplasmic reticulum function?
Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones . It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.
What does the endoplasmic reticulum do quizlet?
What is the function of the Endoplasmic Reticulum? The Endoplasmic Reticulum transports nutrients from one part of the cell to the other .
What are the two main functions of the rough 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 structure and function of endoplasmic reticulum?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism . The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
What are the 3 main functions of the endoplasmic reticulum?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins .
What is the difference between rough 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 is a ribosome simple definition?
ribosome. / (ˈraɪbəˌsəʊm) / noun. any of numerous minute particles in the cytoplasm of cells , either free or attached to the endoplasmic reticulum, that contain RNA and protein and are the site of protein synthesis.
Which is not a function of endoplasmic reticulum?
The rough endoplasmic reticulum is especially prominent in cells such as hepatocytes. The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification.
What do 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).
Which are functions of smooth ER quizlet?
Does the Smooth Endoplasmic Reticulum create steroids? One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids , an essential component of a cell’s outer membrane, and steroids.
What is the difference between smooth and rough endoplasmic reticulum ER )? Quizlet?
What is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum? 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.
What is the purpose of rough and smooth endoplasmic reticulum quizlet?
Terms in this set (10) What is the purpose of rough and smooth endoplasmic reticulum. Rough endoplasmic reticulum processes proteins; smooth endoplasmic reticulum produces fat and breaks down toxins and wastes .
What is the main function of 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.
