Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle prepares proteins into vesicles to transport from one area of a cell to another?
A
gogli apparatus
B
chloroplasts
C
rough ER
D
mitochondrion
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: -The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.

Detailed explanation-3: -COPII-coated vesicles transport cargo proteins from the ER to the Golgi; COPI-coated vesicles transport cargo in the retrograde direction (from the cis-Golgi back to the ER) and between Golgi cisternae; and clathrin-coated vesicles form from the plasma membrane and the TGN to fuse with endosomes or lysosomes (Fig.

Detailed explanation-4: -The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.

Detailed explanation-5: -Proteins and other molecules are transported to the Golgi by packages called vesicles, which fuse with the outermost cisterna, which is known as the ‘cis-face’ of the Golgi, and unload their contents.
