Golgi Apparatus & Lysosomes Flashcards
1
Q
What are the functions of the Golgi apparatus?
A
- Add carbohydrate to proteins to form glycoproteins.
- Produce secretory enzymes.
- Transport, modify and store lipids.
- Form lysosomes.
2
Q
What is the Golgi apparatus?
A
• A group of fluid filled membrane bound flattened sacs.
3
Q
What is the Golgi vesicle?
A
A small fluid filled sac in the cytoplasm, surrounded by a membrane.
4
Q
What is the Golgi vesicle produced by?
A
Golgi apparatus.
5
Q
What is the function of Golgi Vesicles?
A
- Store lipids and proteins made by the Golgi apparatus.
* Transports them out of the cell via the cell surface membrane.
6
Q
How are lysosomes formed?
A
When vesicles produced by the Golgi apparatus contain enzymes such as proteases and lipases.
7
Q
What are the functions of the lysosomes?
A
- Hydrolyse material ingested by phagocytic cells, such as white blood cells and bacteria.
- Release enzymes to the outside of the cell, in order to destroy material around the cell
- Digest worn out organelles so that the useful chemicals they are made of can be re-used.
- Completely break down cells after they have died ( auto-lysis ).
8
Q
Where are lysosomes found in abundance?
A
Secretory cells.
