He flowchart below shows the pathway a protein hormone takes from the site of synthesis to its transport out of the cell. Ribosomes → rough endoplasmic reticulum → vesicle → Golgi apparatus → vesicle → outside the cell

a) Identify where exocytosis begins in this pathway.
How is the protein transported out of the cell?
