What is rough endoplasmic reticulum and its function?

Narration. 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 rough endoplasmic reticulum kid definition?

Lesson Summary 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 are the three main 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 are the major functions of endoplasmic reticulum?

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 are the main function of 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 are the main function of smooth endoplasmic reticulum?

The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.

What substances are secreted by rough endoplasmic reticulum?

Rough endoplasmic reticulum synthesizes and secretes serum proteins (such as albumin) in the liver, and hormones (such as insulin) and other substances (such as milk) in the glands.♦ The smooth endoplasmic reticulum is tubular in form and is involved in the synthesis of phospholipids , the main lipids in cell membranes.

What is an example of an endoplasmic reticulum?

endoplasmic reticulum. The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.

What are the functions of rough ER?

The rough ER’s main function is to help form and store proteins, while the smooth ER store lipids, a type of fat. The whole reason why it’s called “rough” is because the ribosomes attaching to it give it a “bumpy” or “rough” appearance.

What does rough endoplasmic reticulum have attached to it?

Rough endoplasmic reticulum has ribosomes attached with them on their surface which give them granular appearance while smooth endoplasmic reticulum do not have ribosomes attached with them and thus they have smooth, tube-like and uniform appearance.

What is rough endoplasmic reticulum and its function? Narration. 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.
