D11 golgi body

Question 1

How is golgi body formed

Answer 1

Vesciles containing polypeptides,

pinch off from the rough endoplasmic reticulum and fuse

with the stack of membranes which constitute the golgi body

Question 2

What is the structure of the golgi body

5 features

Answer 2

The structure of the golgi body resembles the structure of Endoplasmic Reticulum, It has 5 features:

• Incoming transport vesicle
• Lumen
• Secretory vesicle
• Newly forming vesicle
• Cisternae

Question 3

What are the 5 main functions of the golgi body

Answer 3

1. Proteins are modified and packaged in the Golgi Body Produces secretory enzymes packaged into secretory vesicles
2. Secrete Carbohydrates e.g. for the formation of plant walls
3. Assembles glycoproteins, such as mucin, by combining carbohydrate and protein
4. Transports and stores lipids
5. Forms lysosomes containing digestive enzymes
