What is the difference between the two types of endoplasmic reticulum?

The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.

What is Agranular endoplasmic reticulum?

a·gran·u·lar en·do·plas·mic re·tic·u·lum. endoplasmic reticulum that is lacking in ribosomes; involved in synthesis of complex lipids and fatty acids, detoxification of drugs, carbohydrate synthesis, and sequestering of Ca++. Synonym(s): smooth-surfaced endoplasmic reticulum.

What is the difference between round 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.

What is the difference between rough and smooth 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.

What is the difference between smooth ER rough ER and Golgi apparatus?

Part of the ER is continuous with the nuclear envelope of the cell. More specifically, the density of rough ER is higher near the nucleus and Golgi apparatus whilst the smooth ER seems to be located evenly throughout the cell.

What is the main difference between the ER and the Golgi apparatus?

What is the Difference Between Golgi Apparatus and Endoplasmic Reticulum? Golgi bodies or Golgi apparatus are an arrangement of few fluid-filled dishes whereas ER is a network of tubules and vesicles. Therefore, this is the key difference between Golgi apparatus and endoplasmic reticulum.

Why RER is granular and Ser Agranular?

Answer: Ribosomes are the site of protein synthesis and thus, RER are present in the cells which are actively involved in the protein synthesis and secretion. They are also known as granular ER. They are also called Agranular ER.

What is function of granular 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.

Why is the smooth ER different?

The smooth endoplasmic reticulum (SER) is distinguished from the rough endoplasmic reticulum (RER), the other basic type of endoplasmic reticulum, by its lack of ribosomes, which are protein-synthesizing particles that can be found attached to the outer surface of the RER to give the membrane its “rough” appearance.

What does the endoplasmic reticulum do what is the difference between rough ER and smooth ER What is the ER doing that is different in each case?

Smooth ER provides vesicles for the cis-face of the Golgi apparatus. The rough endoplasmic reticulum is mostly associated with the production, modification, and transfer of proteins. The smooth endoplasmic reticulum is mostly associated with the production of lipids and the storage of calcium ions.

What is the difference in the rough ER and the smooth ER and what is the function of each?

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.
