The Synthesis And Transport Of Proteins- Movement Of Proteins Between Membranes Flashcards
What happens once the proteins are in the ER?
They are transported by vesicles that bud off from the ER and fuse with the Golgi apparatus
What happens as proteins move through the Golgi apparatus?
The protein undergoes post-translational modification
How do proteins move through the Golgi apparatus?
They move through the Golgi discs in vesicles that bud off from one disc and fuse to the next one in the stack.
What do enzymes do in the Golgi apparatus?
They catalyse the addition of various sugars in multiple steps to form the carbohydrates
What is the addition of carbohydrates group?
It is the major modification
What happens when the proteins leave the Golgi apparatus?
They bud off in vesicles that leave the Golgi apparatus take proteins to the plasma membrane and lysosomes. The vesicles move along microtubules and fuse within the cell
