Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelles that has a series of flattened membranes, involved in secretion proteins from cells and in reactions that link sugar to other cellular components?
A
Endoplasmic reticulum
B
Peroxisomes
C
Golgi apparatus
D
Mitochondria
Explanation: 

Detailed explanation-1: -The Golgi apparatus functions as a molecular assembly line in which membrane proteins undergo extensive post-translational modification. Many Golgi reactions involve the addition of sugar residues to membrane proteins and secreted proteins.

Detailed explanation-2: -A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi apparatus prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell.

Detailed explanation-3: -The Golgi apparatus consists of a stack of flattened cisternae and associated vesicles. Proteins and lipids from the ER enter the Golgi apparatus at its cis face and exit at its trans face.

Detailed explanation-4: -The endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins. The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.

Detailed explanation-5: -Golgi apparatus, also called Golgi complex or Golgi body, membrane-bound organelle of eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened, stacked pouches called cisternae.
