Frequently Asked Questions (FAQ’S)
Q1. What are cisternae?
Ans: Cisternae are small collecting vessels that pinch off from
the end of a Golgi body to form a transport vesicle that moves
materials through the cytoplasm
Q2. What is GERL?
Ans: Golgi-associated endoplasmic reticulum involved in the
formation of lysosomes is called GERL.
Q3. What is difference between cisternae of Golgi complex and
those of ER?
Ans: The cisternae of Golgi complex differ from those of ER in the
absence of ribosomes, not associated with protein synthesis, in
cytochemical and biochemical properties, and in concentrations of
Glucose-6-phosphate and choline.
Q4. What is Golgi apparatus?
Ans: A collection of flattened stacks of membranes in the
cytoplasm of eukaryotic cells, functioning in collection, packaging
and distribution of molecules
Q5. What are the main enzymes reported in Golgi body?
Ans: ADPase, ATPase, CTPase, NADPH, Cytochrome C reductase,
UDP-N-acylglucoseamine transferase, glycosyltransferase, and
lactosyltransferase etc.
Q6. What is the main function of Golgi complex?
Ans: The main function of the Golgi complex is the secretion of
enzymes, i.e. cell secretion. They synthesize, transport and
release secretions from the cell.
Q7. Who discovered the Golgi complex?
Ans:
Camilo Golgi in 1898 discovered Golgi complex
in nerve
cells of barn owl and cat.
Q8. How is Golgi body known in the plant cells?
Ans: In plant cells Golgi body is known by dictyosome.
Q9. Name the cells in which Golgi bodies are not found?
Ans: Golgi bodies are not found in prokaryotic cells, mature
vertebrate sperms, red blood cells, and sieve tube cells in plants.
Q10. What cell component is responsible for the acrosome
formation in sperm?
Ans: The cell component responsible for acrosome formation in
sperm is Golgi body.
Q.11: What is Cis – face of Golgi Complex?
Ans: The cis or entry face is the site at which transport besides,
dock with and add their contents to the Golgi cisternae.
Q.12: What are Chaperone proteins?
Ans: Chaperone are proteins that assist the non-covalent folding
or unfolding and the assembly or disassembly of other
macromolecular structures, but do not occur in these structures
when the structures are performing their normal biological
functions.
Q.13: What do Golgi Complex in plant cells mainly produce?
Ans: the Golgi complex in plant cells produces pectin’s and other
polysaccharides specifically needed for plant structure and
function.
Q.14: To what does products of Golgi apparatus fuse with?
Ans: The products exported by Golgi apparatus fuse with plasma
membrane of cells.
Q.15: Why Gentle homogenization is preferred over gradent
homogenization in isolation of Golgi complex?
Ans: Gentle homogenization is preferred to preserve the stacks of
cisternae.
