what is the relation between endoplasmic reticulum golgi apparatus and lysosomes
Answers
Today, scientists know that the endomembrane system includes the endoplasmic reticulum (ER), Golgi apparatus, and lysosomes. Vesiclesalso allow the exchange of membrane components with a cell's plasma membrane.
Hii
Here is your answer -
The Golgi apparatus and Endoplasmic reticulum (ER) are both organelles found in the majority of eukaryotic cells. Lysosomes are membrane-bound organelles containing a repertoire of hydrolytic enzymes called acid hydrolases. These have the ability to digest intracellular macromolecules such as proteins, lipids and sugars.
The functioning of the Golgi apparatus and ER are both so closely linked to the lysosomes that together, these entities compose the endomembrane system. Interestingly, lysosomal formation relies on the joint contribution of the ER and Golgi.
The Golgi is responsible for the formation of lysosomes. When vesicles bud off from the trans-Golgi and fuse with endosomes, lysosomes are formed.
In contrast, the ER is where the lysosomal hydrolases are synthesized. Then they are transported to the Golgi, and are tagged for the lysosomes.
The endomembrane system in eukaryotic cells works together to modify, package, and transport lipids and proteins.
