Why does rough endoplasmic reticulum appear rough under a microscope?
Why does rough endoplasmic reticulum appear rough under a microscope?
RER(rough endoplasmic reticulum) looks rough under a microscope because it has particles called ribosomes attached to its surface.
What gives rough endoplasmic reticulum the rough appearance?
The rough endoplasmic reticulum is made up of membranes which have ribosomes attached to it. This gives it the rough appearance. The rough endoplasmic reticulum also contains a perinuclear space, which is the space between the inner and outer phospholipid membrane. The membrane is continuous to the nuclear membrane.
Why does ER appear rough at times?
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
What is the role of rough 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.
What is the function of SER and RER Class 9?
The functions of SER and RER jointly give a complete idea of the functions performed by the ER as a whole. ER helps in membrane biogenesis. This process refers to the formation of the cell membrane. It is widely known that the cell membrane is made up of lipids and proteins.
What is function of rough ER?
Explanation: The Rough ER which is studded with ribsomes is needed to carry substances, like proteins, to various parts of the cell. These proteins are delivered to other membrane bound organelles like golgi body or transported out of the cell. Endoplasmic reticulum is regarded as the highway of the cell!
What are the two main functions of rough endoplasmic reticulum?
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 is the role of RER and SER?
The presence of ribosomes is actually responsible for the synthesis of the proteins by the RER….Introduction on Rough and Smooth Endoplasmic Reticulum.
