Name the scientist who discovered Golgi apparatus?
A.
Robert Remake
B.
Rudolf Virchow
C.
Camillo Golgi
D.
Theodor Schwann
Answer: Option C
Explanation:
Camillo Golgi was an Italian physician who first discovered Golgi complex, which is a single membrane-bound organelle. It consists of five to eight membrane-bound sacs called cisternae.
Which of the following organelle takes part in the secretion?
A.
Cytoplasm
B.
Ribosomes
C.
ER compartments
D.
Golgi apparatus
Answer: Option D
Explanation:
Golgi apparatus is prominent in cells that are specialized for secretion like goblet cell of intestinal epithelium secrete a large amount of mucus. Cell secretion takes place from trans-Golgi through exocytosis.
The chemical products of the cell are shipped and distributed by?
A.
ER lumen
B.
Golgi apparatus
C.
Lysosome
D.
Endosome
Answer: Option B
Explanation:
Golgi apparatus modifies and transport proteins and lipids that have been built in the endoplasmic reticulum to the outside of the cell or to other locations in the cell.
Which type of glycosylation takes place in the g=Golgi apparatus?
A.
T-linked glycosylation
B.
N-linked glycosylation
C.
O-linked glycosylation
D.
G-glycosylation
Answer: Option C
Explanation:
O-linked glycosylation occurs by the linking of O-linked oligosaccharides to the hydroxyl group of amino acid via N-acetylglucosamine. Proteins undergo O-linked glycosylation in the cisternae of Golgi.
Which of the following is not the function of the Golgi apparatus?
A.
Processing and shorting of glycoprotein
B.
Lipid metabolism
C.
Carbohydrate metabolism
D.
Amino acid metabolism
Answer: Option D
Explanation:
Golgi apparatus involves the metabolism of carbohydrates, and lipids, but not of amino acid, so, amino acid metabolism is incorrect. Synthesis of glycolipids and sorting of glycoprotein also takes place in Golgi apparatus.
