Exocytosis

Question 1

Vesicles (in exocytosis)

Answer 1

Fuses with the plasma membrane

- then substances carried within the vesicles are released

Question 2

Secretion involves:

Answer 2

1. Materials are targeted to vesicles
2. the vesicles move to the proper location
3. Signal trigger the release of materials from the vesicles

Question 3

What happens to materials like neurotransmitters in vesicles

Answer 3

They are loaded into vesicles from cytoplasm to target vesicles

Question 4

What happens to materials like proteins in vesicles

Answer 4

There synthesize in ribosomes linked to the RER

Question 5

What are one of the major purposes for the rough ER

Answer 5

1. completely leave the cell
2. become part of the plasma membrane
3. become part of the lysosome

Question 6

What happens to vesicle containing completed protein

Answer 6

They are sent to the golgi apparatus

Question 7

Goldie apparatus does what to proteins from vesicles

Answer 7

It adds chemical tags to proteins; helps direct them to the proper location

Tags: carbohydrates, lipids, and phosphate groups

Question 8

Various signals can trigger exocytosis like:

Answer 8

Constitutive secretion

Regulative secretion

Question 9

Constituted secretion

Answer 9

Continual release of material from the cell

Question 10

Regulative secretion

Answer 10

Release of material at specific, controlled times from the cell
