Difference Between Lysosomes And Ribosomes




Difference Between Lysosomes And Ribosomes. In this article, you will come to know about what are lysosomes, what are ribosomes, what is the main difference between lysosomes and ribosomes, and a comparison between lysosomes vs ribosomes. They both are organelles present in the living cell with a little difference, which we will discuss below.

Difference Between Lysosomes And Ribosomes:

The main difference between lysosomes and ribosomes is that the lysosomes are the membrane-bound vesicular organelles that are found in eukaryotic cells. On the other hand, ribosomes can be found in both prokaryotic and eukaryotic cells. Lysosomes are composed of protein-membrane and digestive enzymes and ribosomes are composed of rRNA and ribosomal proteins.

What Are Lysosomes?

Lysosomes are vesicular organelles that are membrane-bound. They can be found equally throughout the cytoplasm. They enclose the digestive enzymes that break down the old cells and destroy harmful pathogens. Lysosomes are formed by the Golgi apparatus. The enzymes are produced in the endoplasmic reticulum. They are packed and processed in the Golgi apparatus in the form of small vesicles. These small vesicles are then pinched off from the Golgi apparatus and become the lysosomes. Lysosomes have the thickest membrane and have many small granules containing hydrolytic enzymes. The degradation energy of the lysosomes does not generate any type of energy.


Functions Of Lysosomes:

-Because of their degradation activity, Lysosomes are called a ‘garbage system’ of the cell.
-The main function of lysosomes is to break down unwanted macromolecules.
-Extracellular and intracellular digestion.

What Are Ribosomes?

Ribosomes are the organelles that are found in the cytoplasm with no enclosed membrane. They are small dot-like in shape and have a granular structure. They can be found floating freely in the cytoplasm or sometimes are attached to the endoplasmic reticulum. The main function of ribosomes is to produce proteins. They are around 15 nm in diameter. Ribosomes have 65% of ribonucleic acid (RNA) and 35% of proteins. The RNA present in the ribosomes is called ribosomal RNA (rRNA).

Difference Between Lysosomes And Ribosomes - What are ribosomes

Function Of Ribosomes:

-They take part in protein synthesis.
-Carries the genetic code for protein synthesis from the nucleus to ribosomes.
-Involved in the translation of mRNA.

Main Difference Between Lysosomes And Ribosomes:

-Lysosomes are found in eukaryotic cells
-Ribosomes are found in both eukaryotic and prokaryotic cells.

-Lysosomes are enclosed by a membrane.
-Ribosomes are not enclosed by a membrane.

-Lysosomes are 0.1 to 1.2 μm in size.
-Ribosomes are 20 to 30 nm in size.

-Lysosomes are composed of membrane proteins and digestive enzymes.
-Ribosomes are composed of ribosomal proteins and rRNA.

-Lysosomes are distributed equally throughout the cytoplasm.
-Ribosomes are sometimes attached to the endoplasmic reticulum or remain scattered in the cytoplasm.

-Lysosomes helps in intracellular digestion.
-Ribosomes are involved in protein synthesis and translation of mRNA.
