Endocytosis is an example of which transport mechanism?

Explanation:
Endocytosis is a bulk transport process that uses energy to move material into the cell by wrapping the membrane around the particle and pinching off a vesicle. Because it requires cellular energy (ATP) to rearrange the cytoskeleton and form vesicles, it is a form of active transport. It isn’t osmosis, which is the passive movement of water across a membrane; it isn’t diffusion, which is the passive movement of molecules down their concentration gradient; and it isn’t facilitated diffusion, which uses membrane proteins but does not require energy.
