Q

What is the vesicular transport model in the Golgi apparatus?

A
  • Suggests that the Golgi is static

Packages move through cisternae by vesicles

Q

What is the cisternal maturation model in the Golgi apparatus?

A
  • Suggests that the Golgi is dynamic
    Cisternae progress through apparatus and mature from a cis cisternae to trans cisternae
    (New cisternae form at cis end)
17
Q

What is the current belief about the models of movement in the Golgi?

A

Combination of both

18
Q

How do vesicles reach the correct target?

A

SNAREs

Soluble N-ethylmaleimide

19
Q

What are the two types of SNAREs?

A
  • vSNARE - vesicle SNARE

- tSNARE - target SNAREs

20
Q

Where are the two types of SNAREs found?

A

vSNAREs are found in vesicle membranes

tSNAREs are found in target membrane
