Question

What is Ribosome?

Answer 1

Ribosome : These are the small organelles composed of RNA-rich cytoplasmic granules.

• It is the site of protein synthesis. it is of two types which is given below ;

I. Rough Endoplasmic Reticulum (RER) : It is a vast system of interconnected, membranous, infolded and convoluted sacks, that are located in the cytoplasm.

• RER contains ribosomes, which gives it a rough appearance.
• It transports materials through the cell and helps in protein synthesis.

II. Smooth Endoplasmic Reticulum (SER) : It is a vast system of inconnected, membranous, infolded tubes, which are located in the cytoplasm.

• The space within the SER is called the SER lumen.
• It transports materials through the cell and contains enzymes that produce and digest lipids (fats) and membrane proteins.
• SER and RER and transports the newly-made protein and lipids to the the Golgi body.
