The right answer is Golgi apparatus (which contains vesicles that migrate to the cell membrane).
The new proteins must join very different sites of the cell (and its environment). A sorting and routing system is therefore necessary to ensure that these new proteins gain their destination. In the resource entitled "Membrane transport", we have already pointed out that certain organelles, including the endoplasmic reticulum, the Golgi apparatus, the endosomes, the lysosomes and the secretory vesicles, communicate with each other, but also with the outside of the membrane. cell (by the endocytosis and exocytosis pathway). Their content can be assimilated to the extracellular environment.
