20. How do signal sequences and signal patches differ? 21. What happens to proteins in the Golgi? How and why can this process vary from cell to cell? 22. Connective tissue cells produce extracellular matrix proteins as needed, which are then packaged into vesicles that immediately fuse with the plasma membrane to release the ECM proteins into the ECM. What process is being described?
