Exocytosis is a type of cellular transport that allows materials to move across the plasma membrane of a cell. Which of the statements describe properties of exocytosis? Exocytosis secretes materials from the cell through the fusion of a vesicle with the plasma membrane. Exocytosis engulfs materials into the cell through the pinching off of a vesicle from the plasma membrane. Exocytosis uses membrane channel proteins to import materials into the cell. Exocytosis is the primary method of transporting large molecules into the cell. Exocytosis is the primary method of transporting large molecules out of the cell.
