Answer:
Macromolecules are transported from one space to another through a process of transcytosis or transcellular transport. It consists of a series of steps that will allow the mobility of macromolecules from one extracellular space to another, through the cellular menbrain, through a vesicle formation process. These vesicles maintain a certain load inside. The processes that are generated for the transcytosis process are those of endocytosis and exocytosis.
