Question

Differentiate the rough endoplasmic reticulum from smoth endoplasmic ​

Answer 1

Answer:

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.

Answer 2

Answer:

difference between the smooth endoplasmic reticulum and rough endoplasmic reticulum are summarized below:⬇️

✧ Rough Endoplasmic Reticulum (RER)

• It possesses ribosomes attached to its membrane
• Formed of cisternae and a few tubules.
• It participates in the synthesis of enzymes and proteins.
• It helps in the formation of lysosomes
• It is internal and connected with the nuclear envelope
• Ribophorins are present and help ribosomes attach to ER
• It might develop from the nuclear envelope
• Provides proteins and lipids for Golgi apparatus.

✧ Smooth Endoplasmic Reticulum (SER)

• It does not have ribosomes on its membrane.
• Formed of vesicles and tubules.
• Synthesises glycogen, lipids and steroids.
• Gives rise to Spherosomes/ Oleosomes.
• It is peripheral and may be connected to plasmalemma
• Devoid of Ribophorins.
• Develops from Rough Endoplasmic Reticulum.
• Provides vesicles for cis-face of Golgi apparatus.
