Question

what is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum? question blank 1 of 1

Answer 1

The existence of ribosomes is the primary distinction between RER and SER. When ribosomes attach to an ER's surface, giving it a noticeably rough appearance, the ER is referred to as a "Rough ER." A smooth ER, on the other hand, doesn't have ribosomes on its surface.

What about function of the endoplasmic reticulum?

• The endoplasmic reticulum (ER) performs critical functions, especially in protein synthesis, folding, modification, and trafficking.
• Two forms of ER, known as rough ER (RER) and smooth ER, are distinguished by differences in specific physical and functional features (SER).
• The RER ribosomes, which give the RER a rough appearance, are specialized for the synthesis of proteins with signal sequences that specifically target the ER for processing.
• Proteins synthesized by the RER have specific final destinations such as the cell membrane, the extracellular surface, or the ER itself.
• Sers are involved in the synthesis of lipids such as cholesterol and phospholipids that are used to generate new cell membranes. I'm here.
• In liver cells, SER contributes to the detoxification of drugs and harmful chemicals.
• The sarcoplasmic reticulum is a special type of her SER that regulates the calcium ion concentration within the cytoplasm of striated muscle cells.

Answer 2

In the synthesis and storage of proteins, the smooth and rough endoplasmic reticulum both play a role. The fundamental distinction between the two is that one has ribosomes while the other has not.

Ribosomes are present on the rough endoplasmic reticulum's (RER) surface. The RER looks "rough" because of this. ER rough resembles sheets. Protein synthesis and packaging are done by the RER. The nuclear membrane is where the RER is affixed. Typically, the Golgi apparatus is located on the opposite side of the RER.

Ribosomes are absent from the smooth endoplasmic reticulum (SER). The Smooth ER resembles tubes more. Proteins and lipids are stored with the aid of the SER. Oil-producing cells have a greater SER ratio than other types of cells.
