exocytosis & organelles

Question 1

exocytosis

Answer 1

refers to the exit of protein
- the secretory gland containing protein fuses with the plasma membrane releasing its contents
- mitochondria provides energy for this process

Question 2

summarise the role:
1. mitochondria
2. nucleus

Answer 2

1. Converts glucose to ATP which is used in the transport and packaging of protein
2. nucleus
   - control centre for cells
   - contains genetic information
   - where transcription and RNA processing occur

Question 3

summarise the role:
3. ribosome
4. rough endoplasmic reticulum

Answer 3

3. modifies and transports proteins
   4.

Question 4

summarise roles:
5. transport vesicle
6. golgi apparatus

Answer 4

5. transport vesicle
   - delivers proteins to destinations besides the cell membrane
6. golgi apparatus
   - packages proteins into vesicles

Question 5

summarise roles:
7. secretory vesicle
8. plasma membrane

Answer 5

7. secretory vesicle
   - exports protein from cells by exocytosis
8. plasma membrane
   - facilitates in the release of proteins from the cell by exocytosis

Question 6

organelle order in protein synthesis

Answer 6

1. mitochondria
2. nucleus
3. ribosome
4. rough endoplasmic reticulum
5. transport vesicle
6. golgi apparatus
7. secretory vesicle
8. plasma membrane
