What is the function of vesicles in the synthesis of proteins and the release

The function of vesicle in the synthesis of protein is for the transport of the protein to corresponding organelles in the cell.

Explanation: Vesicle means a sac-like structure in the cell. It can contain many biochemicals molecules. The proteins are synthesized on ribosomes of the endoplasmic reticulum are packed temporary in vesicles. These temporary vesicles are transported to Golgi apparatus for the modification of proteins. After modification, proteins are packed in vesicle known as Golgi vesicles which bud from outer layers of Golgi apparatus. These Golgi vesicles are then transported to intercellular locations and intracellular locations.

The Golgi apparatus functions in close association with the rough endoplasmic reticulum. When a protein is formed in the rough endoplasmic reticulum, the formation of transition vesicles takes place. This vesicle or sac floats via the cytoplasm to the Golgi apparatus and is then absorbed.

The vesicles transport the newly formed proteins to the Golgi apparatus. After the modification of the proteins is done by the Golgi apparatus, the vesicles transport the modified proteins to the membrane of the cell, where they are discharged.
