Secretory Pathway Flashcards
1
Q
Many secreted proteins are synthesised as
A
inactive precursors and require proteolytic cleavage to produce active proteins
2
Q
Examples of secreted proteins?
A
peptide hormones and digestive enzymes
3
Q
The secretory pathway 1
A
Secreted proteins are translated in ribosomes on the RER and enter its lumen.
4
Q
The secretory pathway 2
A
The proteins move through the Golgi apparatus and are then packaged into secretory vesicles
5
Q
The secretory pathway 3
A
These vesicles move to and fuse with the plasma membrane, releasing the proteins out of the cell
