What is the function of the rough endoplasmic reticulum ER?

What is the function of the rough endoplasmic reticulum 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.

Which are functions of the endoplasmic reticulum ER quizlet?

endoplasmic reticulum- A system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.

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. Ribosomes on the rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for the assembly of many proteins.

What is the difference between smooth and rough endoplasmic reticulum 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.

Which of the following is a function of the rough ER quizlet?

Which of the following is a function of the rough endoplasmic reticulum? The rough ER synthesizes all proteins secreted from the cell; it also functions as the cell’s “membrane factory” because integral proteins and phospholipids that form part of all cellular membranes are manufactured there.

How is rough ER different from smooth ER What functions do they perform in a 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 are the functions of lysosomes and ribosomes?

Difference Between Lysosomes and Ribosomes

Lysosome Ribosome
They consist of hydrolytic enzymes that break down molecules such as peptides, proteins, nucleic acids, and lipids. They consist of ribosomal RNA and ribosomal proteins that help in synthesizing proteins from the messenger RNA.

What is the difference between rough and smooth endoplasmic reticulum?

The main difference between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER), is that RER is studded with membrane-bound ribosomes , while SER lacks this organelle. Ribosomes are concerned with protein synthesis. RER is more prominent in liver cells, as they are concerned with the production of proteins.

What are facts about endoplasmic reticulum?

endoplasmic reticulum (ER) A system of membranes within the cytoplasm of plant and animal cells. It forms a link between the cell and nuclear membranes (see cisterna ) and is the site of protein synthesis.

What does the rough endoplasmic reticulum interact with?

It is called ‘rough’ endoplasmic reticulum because it is studded on its outer surface (the surface in contact with the cytosol) with ribosomes . These are called membrane bound ribosomes and are firmly attached to the outer cytosolic side of the ER About 13 million ribosomes are present on the RER in the average liver cell.

What is the rough ER job?

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.
