Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where are proteins modified and packaged into vesicles?
A
Ribosomes
B
Golgi Body/Apparatus
C
rER
D
sER
Explanation: 

Detailed explanation-1: -Proteins are sorted into the regulated secretory pathway in the trans Golgi network, where they are packaged into specialized secretory vesicles. These secretory vesicles, which are larger than other transport vesicles, store their contents until specific signals direct their fusion with the plasma membrane.

Detailed explanation-2: -The Golgi apparatus is often found in close proximity to the ER in cells. Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface.

Detailed explanation-3: -Definition. A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

Detailed explanation-4: -The endomembrane system (endo-= “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.

Detailed explanation-5: -The Golgi apparatus is a cellular organelle responsible for the modification and trafficking of proteins to other organelles. Proteins translated within the rough endoplasmic reticulum are transferred to the Golgi. From there they are modified and packaged into vesicles for distribution.
