Question

Which of the following organelles is involved in the modification and routing of molecules to the exterior of the cell or to various locations inside the cell
a. Lysosome
b. Peroxisome
c. Endoplasmic reticulum
d. Mitochondrion
e. Golgi apparatus

Answer 1

Answer:

The correct answer is e. Golgi apparatus

Explanation:

Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.  

The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.

Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.

Therefore the correct answer is e. Golgi apparatus.
