Movement of proteins between membranes Flashcards
1
Q
What happens when proteins are in the ER?
A
Transported by vesicles that bud off from the ER and fuse with the Golgi apparatus.
2
Q
What happens as proteins move through the Golgi apparatus?
A
Undergo post-translational modification.
3
Q
What is the major modification to proteins?
A
Addition of carbohydrate groups.
4
Q
What happens to vesicles that leave the Golgi apparatus.
A
Take proteins to plasma membrane and lysosomes.
5
Q
What is function of a lysosome?
A
Membrane bound organelles that contain a variety of hydrolases (enzyme that catalyse the cleavage of a covalent bond with water)
6
Q
Where do vesicles move along?
A
Microtubules and to other membranes and fuse with them within the cell.
