Exocytosis is the primary method of transporting large molecules out of the cells.
Exocytosis secretes materials from the cell through the fusion of a vesicle with the plasma membrane. example- newly made proteins inside cell are packed in vesicles, these vesicle fuse with plasma membrane and the proteins are released outside the cell.

Watch the animation, then answer the questions below
A primary active transport process is one in which
the plasma membrane folds inward to form a vesicle containing extracellular material
molecules pass directly through the phospholipid bilayer of the plasma membrane
molecules move through transport proteins that have been activated by ATP
molecules move across the plasma membrane without an input of energy
an intracelular vesicle fuses with the plasma membrane and releases its contents to the extracellular fuld

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...
