1
Q
- Once the proteins are in the ER…
A
They are transported by vesicles that bud off from the ER and fuse with the golgi apparatus.
2
Q
- As proteins move through the golgi apparatus…
A
They undergo post-translational modification. The addition of carbohydrate groups is the major modification.
3
Q
Molecules move through the golgi discs in…
A
Vesicles that bud off from one disc and fuse to the next one in the stack.
4
Q
- Vesicles that leave the golgi apparatus take proteins to…
A
The plasma membrane and lysosomes.
5
Q
Vesicles move along…
A
Microtubules to other membranes and fuse with them within the cell.
6
Q
Enzymes catalyse the…
A
