What are the structural and functional differences between rough and smooth ER?

Its rough appearance is given by the bound ribosomes on its surface. Rough ER synthesizes and stores proteins. Smooth ER, on the other hand, helps in the storage of proteins and lipids. The main difference between smooth and rough ER is that smooth ER lacks bound ribosomes whereas rough ER is bound with ribosomes.

What are the structural and functional differences between rough and smooth endoplasmic reticulum quizlet?

The primary distinction between rough and smooth ER is the presence of bound ribosomes on the rough ER. Both types of ER make phospholipids, but membrane proteins and secretory proteins are all produced by the ribosomes on the rough ER.

Which of the following functional differences between the rough and smooth ER is explained?

Answer. Explanation: Both the smooth and rough endoplasmic reticulum help in the production and storage of proteins The main difference is that one contains ribosomes on it and the other does not. The rough endoplasmic reticulum (RER) has ribosomes on its surface.

What is the difference between smooth and rough ER?

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 difference between rough and smooth ER 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.

What are the functions of smooth and rough ER?

The rough endoplasmic reticulum contains ribosomes and makes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of smooth ER are found in cells that participate in lipid metabolism and detoxify the body, such as liver cells.

What is the function of smooth ER?

The smooth ER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol.

What is the function of rough ER?

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 structure of rough ER?

The rough endoplasmic reticulum is largely made of sheets – a two-dimensional array of flattened sacs that extend across the cytoplasm. In addition to ribosomes, these membranes contain an important protein complex called the translocon, which is necessary for protein translation within the rough ER.

How does the structure of the rough ER aid in the function?

How does the structure of the rough ER aid in the function? Rough ER is a network of folded membranes. These folds allow for an increased surface area to create more proteins.
