Q3. The face of the Golgi apparatus that receives vesicles from the ER is called:
- Trans face
- Cis face
- Medial face
- Lateral face
Q4. Which of the following is NOT a function of the Golgi apparatus?
- Modification of proteins

- Synthesis of proteins
- Formation of lysosomes
Q5. The Golgi apparatus is particularly abundant in cells that:

Short Answer Questions
Q6. Describe the structure of the Golgi apparatus. What is the significance of its cis and trans faces?
Q7. Explain the role of the Golgi apparatus in modifying proteins. What types of modifications occur?
Q8. How does the Golgi apparatus contribute to the formation of lysosomes? Explain.
Q9. Compare the functions of the cis face and the trans face of the Golgi apparatus.
Long Answer Questions
Q10. Draw a well-labelled diagram of the Golgi apparatus showing the cis face, medial cisternae, trans face, and secretory vesicles. Explain how proteins move through the Golgi apparatus from the cis face to the trans face.
Q11. Describe the secretory pathway in a cell. Trace the journey of a protein from its synthesis in the ribosome to its secretion outside the cell, mentioning the role of each organelle involved.
APPLICATION / ANALYSIS
Q12. A pharmaceutical company is developing a drug that specifically targets the Golgi apparatus of cancer cells.
(a) Why would disrupting the Golgi apparatus be particularly harmful to rapidly dividing cancer cells?
(b) If the drug prevents the Golgi from packaging proteins into vesicles, how would this affect the cancer cell's ability to divide and spread?
(c) What potential side effects might this drug have on normal cells, and why?
Q13. In a school biology project, a student is asked to explain why pancreatic cells (which secrete digestive enzymes) have a very well-developed Golgi apparatus, while muscle cells do not.
(a) Explain the relationship between the function of pancreatic cells and the abundance of Golgi apparatus.
(b) Why do muscle cells have less prominent Golgi apparatus compared to pancreatic cells?
(c) If a mutation caused pancreatic cells to have a poorly developed Golgi apparatus, what digestive problems might result?
