what is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
321366
There are two basic types of ER. Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.

The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae (in the RER), and tubular structures in the SER.

Cell membrane refers to the semipermeable membrane surrounding the cytoplasm of a cell while nuclear membrane refers to a double membrane, enclosing a cell nucleus and having its outer part continuous with the endoplasmic reticulum. Thus, this is the main difference between cell membrane and nuclear membrane.

As adjectives the difference between rough and harsh is that rough is having a texture that has much friction not smooth; uneven while harsh is unpleasantly rough to the touch or other senses.

Which one of the following functions is not carried out by smooth endoplasmic reticulum? Explanation: Smooth Endoplasmic Reticulumdoes not contain ribosomes on its surface for which it is regarded as smooth. So, proteins cannotbe synthesised by SER provided protein synthesis is the primary task of ribosomes.

Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. ... Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids.

A. What is the difference between the rough and smooth ER? Rough ER's have ribosomes on the surface and produce large amounts of proteins for export. Smooth ER's contain a collection of specialized enzymes and does not have ribosomes on its surface.

The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. Differences in certain physical and functional characteristics distinguish the two types of ER, known as rough ER (RER) and smooth ER (SER).

Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes. ... Rough ER: As membrane proteins grow from ribosomes on rough ER, the proteins are embedded into the rough ER membrane.

Ribosomes on the rough endoplasmic reticulum are called 'membrane bound' and are responsible for the assembly of many proteins. This process is called translation. Certain cells of the pancreas and digestive tract produce a high volume of protein as enzymes.

Answer and Explanation: The proteins that are synthesized by the rough ER are proteins destined for secretion or to become part of the endomembrane system. Ribosomes on the...

Chemical Composition: Endoplasmic reticular membranes contain high lipid content in relation to its protein partners. The common lipids found are phospholipids, phosphotidyl inositol, neutral lipids, sulfolipids, cholesterol and some phytosterols.

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.

Smooth Endoplasmic Reticulum. The SER has a variety of functions that are often more prominent in certain cell types whose roles require an enhanced SER ability. Four common functions are the mobilization of glucose from glycogen, calcium storage, drug detoxification, and the synthesis of lipids.

Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.

Smooth Endoplasmic Reticulum: Throughout the eukaryotic cell, especially those responsible for the production of hormones and other secretory products, is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short.

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.
