1) b) iii) movement of proteins

Question 1

once the proteins are in the __________ _________, they are _________ by _________ that _____ ____ from the _______ ________ and ____ with the Golgi apparatus

Answer 1

Once the proteins are in the endoplasmic reticulum, they are transported by vesicles that bud off from the Endoplasmic reticulum and fuse with the Golgi apparatus.

Question 2

As proteins move through the Golgi apparatus they undergo what?

Answer 2

As proteins move through the Golgi apparatus they undergo Post translational modification

Question 3

What is the major modifications of proteins as they move through the Golgi apparatus?

Answer 3

The addition of carbohydrate groups - major modification.

Question 4

Describe how molecules move through Golgi apparatus and what happens during this process

Answer 4

Molecules move through the Golgi discs in vesicles that bud off from one disc and fuse to the next one in a stack.
Enzymes catalyse the addition of various sugars in multiple steps to form the carbohydrates.

Question 5

What are the fates of Vesicles (proteins) as they leave the Golgi apparatus?

Answer 5

Vesicles that leave the Golgi apparatus take proteins to the plasma membrane
AND
lysosomes.

Question 6

Vesicles move along ________ to other ___________ and _____ with them within the cell

Answer 6

Vesicles move along microtubules to other membranes and fuse with them within the cell
