Question

GERL is associated with
A. Lysosome
B. Golgi body
C. Mitochondrion
D. Lomasome

Answer 1

Hint: A complex of cell organelles to transport substances in and out of the cell. It is composed of those cell organelles whose main function is to transport the nutrients in the cells and also is responsible for the transfer of proteins in the cells.

Complete answer:
GERL is a Golgi associated endoplasmic reticulum from which lysosome forms. The Golgi system is connected with the endoplasmic reticulum which produces lysosomes. The acronym GERL stands for Golgi-Endoplasmic reticulum-Lysosomal complex. These organelles form a system in the cell to perform endocytosis and exocytosis functions.

Additional Information: -The Golgi apparatus is made up of cisternae that originated from the vesicles that bud off from the endoplasmic reticulum.
-The Golgi apparatus is the organelle referred to as the package center of the cell since the main function is to package molecules for secretion.
-The endoplasmic reticulum is a network of flattened sacs in which the membranes are connected to the nuclear membrane.
-There are two types of endoplasmic reticulum: rough (RER) at the smooth endoplasmic reticulum (SER).
-RER is involved in protein synthesis and secretion while SER is involved in lipid synthesis, transportation, etc.
-The lysosome is a spherical organelle containing a wide range of digestive enzymes.
-The digestive enzymes are used mainly for the digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses and bacteria.
So, the correct answer is the ‘Golgi body’.

Note: Endocytosis is the transport of macromolecules, large particles, and polar substances that cannot enter the cell through the non-polar membrane whereas exocytosis is the transport of molecules or particles outside of the cell. They both require the expenditure of energy in the form of ATP.
