STRUCTURE AND FUNCTION OF THE CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Structure in a cell that receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell.
A
Golgi Body
B
Endoplasmic Reticulum
C
Mitochondria
D
Cell Wall
Explanation: 

Detailed explanation-1: -The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.

Detailed explanation-2: -Proteins Leave the ER in COPII-coated Transport Vesicles To initiate their journey along the biosynthetic-secretory pathway, proteins that have entered the ER and are destined for the Golgi apparatus or beyond are first packaged into small COPII-coated transport vesicles.

Detailed explanation-3: -Plasma membrane and lysosomal proteins also travel from the rough ER to the Golgi and then to their final destinations. Still other proteins travel through the initial steps of the secretory pathway but are then retained and function within either the ER or the Golgi apparatus.

Detailed explanation-4: -A protein called coat protein II (COPII; green) forms vesicles that transport from the endoplasmic reticulum (ER) to the Golgi.
