Question

What is endoplasmic reticulum brief explaination

Answer 1

endoplasmic reticulam is a cell organelle which membrane bound structure. it is of two type -
1.smooth
2.rough
a) smooth ER is that which do not contain ribosomes
b) rough which contain ribosomes

Answer 2

Answer:

Endoplasmic Reticulum -

• The endoplasmic reticulum are tiny tubular structures scattered inside the cytoplasm.
• The endoplasmic reticulum divides the intracellular space into two distinct compartments that is luminal and extraluminal compartment.
• The luminal part is inside the endoplasmic reticulum whereas the extraluminal part is the cytoplasm.
• There are two types of endoplasmic reticulum namely rough endoplasmic reticulum, in short called as, RER and smooth endoplasmic reticulum, in short called as, SER.
• The endoplasmic reticulum bearing ribosomes on their surface is called a rough endoplasmic reticulum.
• The endoplasmic reticulum whose surface does not bear ribosomes, and look smooth because of the absence of ribosomes, are called smooth endoplasmic reticulum.
• The rough endoplasmic reticulum is actively involved in protein synthesis and secretion.
• The smooth endoplasmic reticulum is a site for lipids synthesis.
